Dave is first-rate -- professional, knowledgeable, helpful, customer-focused, friendly. The reviews say it all!

This guy a literally a complete clown. I pulled up but he wasn't there so I called him he said don't worry I'll fix next week on my day off. Monday I texted him hey just a quick reminder if we are still on don't reply til Wednesday and said yes sir I have the parts for your car. Thursday come he doesn't reply all day then said tomorrow I'll be free to do at 6pm. Now it's Friday past 6pm this guy don't even have courtesy or professionalism to even give back a simple reply. Idk how the fuck he got 5 stars. This guy is a complete joke and waste of time. Don't even bother. read more

I reached out in Feb 2026 in regard to a Lexus GX460 needing the HVAC control module fixed, spoke with the owner. He walked us through trouble shooting. It still wasn't working, he gave us the address of his shop, an estimate and said he would have it fixed within a few days and ship the HVAC control module back to us. We sent the unit out and Dave never answered the phone or texts again. We are now out the HVAC control module for a customer's vehicle while Dave is out there scamming people left and right. He needs to be shut down or at the very least people be warned that Navigation Services is not a legit business, they are thieves. Do not trust them. We are a reputable business in Newbury Park and do not do business with scam artists. Lesson learned the hard way unfortunately. For anyone looking to do business or have services done with this "company" beware. read more

I came back to have CarPlay installed in my mom's 2010 RAV4, and once again Dave did an amazing job at an unbeatable price. He also helped hardwire the dashcam, and everything looks so clean and neat now. Very professional service -- truly 5 stars! read more

Excellent! My 2009 IS250 touchscreen sopped working, I could not even adjust my AC and my radio was intermittent. Since I have some limitations, David drove to my place last Sunday and was able to resolve the issue without the games that the dealers play, or other places servicing Lexus. Super knowledgeable and respectful, did not rip me me off and treated me with the respect. Things are working fine now and the fix cost was worth it. read more

Excellent! The slogan on his receipt rings true: "Professional and Reliable Services at Reasonable Prices". Dave repaired my Lexus IS touchscreen (a common defect in these cars), repaired the CD player, and updated my GPS maps. Seriously, this would have cost 12-15 times more at a dealer, and I'm guessing 4-6 times more if you could find another private shop that could do all of these repairs. After chatting with him, I found out he holds both electrical and mechanical engineering degrees! What more do you want? read more

Dave is great, I have referred many other Lexus owners to him to get the same custom work I had done as well, a few people I know have made 3+ hour long commutes just to see him. I have heard nothing but positive things from those who I have referred as well and I would recommend him to anyone in the Southern California area. read more

I am truly amazed that someone like Dave exists! I was stressed out bc my Lexus IS250 touchscreen stopped working. Called around and the estimates to fix were over $1K!!! I stumbled upon some forums that highly recommended a guy in Garden Grove and they were right! He fixed my screen in 20 min and the cost was super low... couldn't believe it. He's such a pro and very kind. God surely blessed him with amazing skills. Go to Dave and he'll fix your issue and give you back your piece of mind. read more

For the past 3 years on my 2007 Lexus IS250 my Spedometer Needle and Tachometer needle has been out. Just last night it started to bug me. I was lucky enough to come across Dave. Within i want to say...15 minutes at most. I was driving away from his place a satisfied customer! read more

So thankful to have found @navigation_services to repair my navigation digitizer. My touch screen magically stopped working when it was in the dealerships possession. Not happy about the whole situation with that... but it is what it is. Not paying over $2,500+ to Lexus for a new one. Dave not only fixed my navigation, but also my mph and rpm needles that gave out prior. All for $200! And lives 10 minutes from Disneyland! So any of my Lexus people, ...if this ever happens to you.

I would think twice before you take your car to this guy. This guy remodified our 2017 lexus instrument cluster. Over short time the panel completely went blank. We contacted this guy and he promised to take care of it as soon as possible he also promised to order a new one and he never did and stopped responding to our texts and phone calls and he lied to us. Also this just disappoints me because we had to spend a lot of money by ourselves to get a new panel. We couldn't drive the car. After all we spent $650 to send it to a real repair company not like crooks like him. His service is very unreliable and we are extremely disappointed. read more

My speedometer needles on my IS350 were flickering for awhile and eventually my touch screen gave out too. Gave Dave a text and he was very responsive and helpful, got an appointment the same day and he had me in and out in about an hour like he said he would! He's a man of his word and is reliable, also threw in some extras for me which I really appreciated. He's a car guy, and his conversations are really interesting. Bonus eye candy RCF in the driveway . Very good prices, will definitely come back if I need anything! read more

Getting my car serviced by Dave was truly a 5-star experience! Texted Dave to help me fix my black navigation screen and unresponsive touchscreen on my 2008 Lexus is250. After he got the screen back to life the navigation part still wasn't working. He told me to bring it back to his place another time to get it fixed. When I showed up to our appointment, he did more than get the navigation back up. He helped me with my airbag light, and also helped me change out my power steering ecu which fixed my power steering issue! I was driving with no power steering so I was extremely happy to have that problem fixed. When I asked him how much I owed for his extra services, he said no charge! But I was so happy with my experience I had to give him tip. Before leaving, I also had a problem with my rear window unable to open from the driver side door. He fixed that issue as well! My entire appointment with Dave was no longer than one hour, and I feel like I'm driving a new car again. He's been working with Lexus vehicles for 10+ years. I highly recommend Dave's services for your Lexus. Just shoot him a text! read more

Dave was awesome and super communicative. Needed the LED's on the needs of my ISF replaced and he was able to knock it out in about 30 minutes! Yes, he does work out of his house but I didn't feel uneasy at all. Super cheerful guy - if I ever need anything else like this work done again I know who I'm going to. read more

At first I thought Dave's Craigslist post was too good to be true: $150 Lexus navigation repair! Every Lexus dealership would quote me $2400 for repair! I finally decided to come to him and he reinstalling my navigation within 30 minutes. They take cash or card and they provide you a receipt and 2 year warranty (unlike Lexus's 1 year warranty). More importantly he's a very nice guy, no hassling and very honest. If you have issues with your Lexus navigation you MUST see him or expect to spend $$$ at the dealership. read more

Dave is very professional with his work. It was easy to set up an appointment over the phone and responsive communication through text messages. Dave showed up on time and and took only about 20mins to repair my navigation touch screen. The is350 is notorious for unresponsive touch screen after several years of usage. First i was skeptical about the repair because my interior dash is in pristine condition, Dave assured me that the dash will remain pristine after the repair. I took a chance and trust Dave to fix the screen. He kept all the parts intact and fixed my screen digitalizer. Happy customer here, I highly recommend Dave for this Navigation work, money well spent. read more

Quick and excellent service. Good communication. Would give more stars if I could. Used original parts.

After my Toyota Prius GPS touchscreen went out I was afraid that I cannot use the radio and the AC. Lucky I found Dave. He's honest and did a great job. His fee was more than reasonable. So I tipped him for his work. Forget the dealership. Call him first and see if he can fix your issues. read more

I found Dave in the car forums and seemed like a very knowledgeable member already so I contacted him there. Little did I know that he actually runs this business, excellently I must say which prompted me to open a yelp account and write a review of my experience with him. As with all the positive reviews, my experience was no different! Background: My 2007 Lexus IS250 suffered from the infamous burnt out gauge cluster needle backlighting. Rather than remove the gauge cluster from the car (intimidating), ship it out of state (rendering my car un-drivable), and pay lots of money for the repair, I was looking for a cheaper and local solution. Thankfully I found Dave who is 5 miles away from me, said he can replace the surface mount LEDs within 40 mins, including removal and installation, AND all be done under half the price of the competitors! I went ahead and scheduled an appointment based on the reviews here and am very glad I did. From the minute I met Dave he was very professional and obviously skilled with the IS platform (he has a beautiful IS350 himself). He removed the gauge cluster in under 5 minutes all while talking to me! Bringing it over to his work bench he was able to remove all 4 needles to replace the LEDs to the color of my choice. I chose blue instead of the standard white (pictures do not do this color justice). Within half an hour, using miniature tweezers to install the ultra small Samsung LEDs, seeing him push solder and flux through the board, and calibrating the needles to zero with precision, the gauge cluster was repaired and more beautiful than ever! We were chatting throughout the entire process too, being that we both went to the same college and have similar electrical engineering backgrounds (he obviously has better soldering skill). Dave is a standup guy with all the technical knowledge and right tools of the trade to get the job done properly. He uses high quality products for his work such as correct ROHS compliant solder, and even bench tested the gauge cluster before reinstallation to ensure proper function. His prices are very competitive and I highly recommend his service to anyone! read more

All these 5 star ratings are true and not exaggerated. Dave quickly removed, serviced, and replaced my dead navigation touch screen, then reassembled my dashboard carefully, avoiding damage to the wood trim in my 2007 Lexus RX350. The job was finished, complete with receipt, in 50 minutes. On our 48 mile return trip home not a rattle was heard. Six days later ALL functions perform perfectly including an updated Navigation disc which Dave installed gratis! The full cost was hundreds and hundreds less than a local mechanic's estimate with a much much better guarantee. I am grateful to Dave for extending the useful life of the vehicle I've loved for 15 years. P.S. I was so excited I forgot to take an 'after' picture. I assure you it looks as good as before. read more

Dave is a true professional in the sense he puts the clients' needs and customer service first. I got my tundra back from the dealership today after they installed a supercharger and they said they had to remove the connectors that powered the amp to my aftermarket stereo system and I would need to go back to the place that I had the system installed for them to hook it back up. This was Saturday evening, and the 1 hour drive home with traffic without music and two young kids in the back screaming got me really impatient to get this handled Asap!!! After getting the kids down for bed (745 pm), I jumped on Yelp to see if I could get this done on Sunday, knowing the shop that installed my stereo would closed that day and came across Dave's yelp page. I texted the number to see his availability and within 1 minute he responded. We went back and forth via text so I could try my best to explain the situation to him. He concluded that it would be an easy fix and told me he would take a look at it for me if i would be willing to meet him. (I think he could tell I really wanted to fix the situation asap, and he was right.) This was around 830 pm. I rushed out of the house and made the trip to meet him. When I arrived I could tell he had friends or family over but stopped what he was doing to inspect my situation. He brought out his tools and within 10 mins the situation had been resolved. Stereo was working again and I was very happy. I asked Dave if there was a bank close by since rushing out of the house I forgot to bring money with me and he told me don't worry about it; it was nothing. Before texting Dave I read basically all the Yelp reviews and a common theme was that he was honest and reliable and I have to say first hand, that definitely was the case. For someone like myself that is not savvy when it comes to this type of stuff I am always weary and try to do as much research as possible so I don't get screwed over. I came into this looking to spend 100 - 200 (worth it for me) to resolve the situation. And for him to make an exception to meet me this late on a Saturday while he has friend and family over shows and charges me nothing, shows me what type of person he is. If any one has any doubt about his work or fairness, don't!! I wish you Dave all the success and thanks again for helping an impatient client. read more

My lexus IS250 touch screen died on me last week and i've been stressing about having to spend $2500 to fix it. Luckily I did some research and found Dave's advertisement on CL! I text Dave to schedudle an appointment, and he responded back immediately! I live in San Diego and he lives in Orange County, he was able to arrange a date to come down to San Diego to fix it for me, YES he does MOBILE SERVICE TOO!! He arrived at my house EXACTLY at 9:00AM, as promised. He checked out my navigation and knew immediately what was wrong with it. He went straight to work and fixed everything within 20-30 minutes, AMAZING!! Dave is extremely talented and intelligent, he took off my dash board/panals within seconds without any damage! He makes it seem so easy, like playing leggos. As if i wasn't already satisfied with his service, he then updated my navigation system, YASSS!!! Definately would recommend all my friends and family to him for their car electronic needs! read more

Believe the hype!!! If I could give Navigation Services 6 stars, I would do so. Dave is a very honest individual who provides an incredible service for an unbeatable price!!! While dealerships would charge $2K+, Dave does the service for less than 1/10th of what they would charge and gets it done in 30 minutes. After watching a YouTube video on how to repair the IS250 navigation screen (my NAV system was unresponsive to the touch) yesterday (August 11th), I thought I could do the repair on my own - because who would pay a dealership $2K+ when they can fix it for free. After spending a few hours driving around to get the equipment and tools needed for the job and trying to do the actual work, I realized that this knucklehead wasn't meant to be a mechanic. So out of anxiety of getting it replaced immediately and my boss (wife) yelling at me for ruining the dashboard (stripped away quite a bit of the melting rubber around the dash trying to repair the NAV), I looked at Yelp and noticed the 5-star ratings for Navigation Services. I called Dave and left a message and he got back to me later saying that he could do the work today (August 12th). I just got back about an hour ago from the repair and was thrilled that the problem was fixed. The touch screen works like new and now I can drive around with the map and have the A/C controlled (versus on full blast when the NAV was not working). For those debating to try to fix it themselves, don't listen to your inner voice or the YouTube videos. If you're in the area, it's a NO BRAINER!!! Just go to Navigation Services and you won't regret it!!! I know the price Dave charges seems too good to be true. While the price is very good, the great thing is that it is true!!! Almost forgot, they take cash, check, PayPal, Venmo, and a few other payment services so easy to make payment. Thank you, Dave, for saving my NAV and my weekend! Time to go return all the equipment that I don't need now! read more

I had been driving my IS250 around for several years without a functioning GPS since the screen was still functioning to control the AC and audio, and rearview camera. When I pressed the map button, it displayed the message "external unit not connected", and the dealership told me I had to replace the unit which is several thousand bucks to replace the unit so I said screw that, I use google maps anyways! 2 weeks ago the screen goes completely black and Im stuck without AC during the heatwave with my French Bulldog panting in the car at the In n Out drive through. After reaching out to 2 other people that repair navigation units, I almost gave up before finding Dave's listing on craigslist. Called him around 4:45 pm, said he could do it around 5:30 that same day, and by 6:30 he had fixed the navi unit, the board, and also updated me to the current map version! His work comes with a warranty as well. Super knowledgeable. I think he is a magician actually. Can't recommend him enough. read more

Dave is a beast! He was able to swap out my brother's ISF tach and speedo lights. They look so much better and he did it in 30 minutes. Super fast service and I was talking to him the whole time so even as I was distracting him he was still able to do an amazing job. He even upgraded the navigation CD for free. He is super knowledgeable. read more

Dave is simply incredible. I was researching various shops to install an aftermarket headunit in my Lexus RC. All of the shops quoted me prices that were above my budget, until I met Dave. I couldn't believe it when he quoted me such a low price. I expected it to be one of those "you get what you pay for" situations. Nevertheless, I ended up scheduling a meeting with Dave (super fast and easy). When I arrived with my car and the headunit, he was prepared and told me it would take him two hours to install everything. I returned to see the finished product and, wow, he outdid any shop! He made certain that all of the cables were hidden, and that the extra USB cable was inside the glove box rather than hanging out like other shops would. Now comes the part that distinguishes him as a true professional. During the installation, Dave mentioned that he couldn't get the backup camera or the center console touchpad to work with the new headunit. I contacted (Lexion), the screen's manufacturer, to see if there was a way to make those functions work properly. Because the company is based in Korea, they did not contact me until late Saturday night, around 8:00 PM. I contacted Dave to schedule an appointment to fix the problems with my screen. To my surprise, he responded within minutes and stated that he could do the job (which implied removing the screen and rewiring a connector) right away!I drove, and he fixed the problem at no extra charge. I offered him money as a tip for his excellent service, but he refused! You simply cannot find an honest, hard working person like Dave anymore! read more

Can't say enough about the speed, efficiency and quality of work from Dave. Navigation screen was completly frozen on my GS 460. After I accidentally un-paired my phone, I was completely hosed and needed a quick solution. Texted Dave and we made an appointment for the next afternoon. Drove to his place and he went right to work - had my nav unit out of the dash in no time. Made the repairs right on the back deck of his impressive Lexus RX portable shop, then put it all back together and reinstalled it without a hitch. He then updated my Navigation map, and the very best of all... 100% of my radio and satellite pre-sets were all completely intact! Thank you Dave! read more
