    My infotainment system broke down and I was looking for a replacement and I consulted two different…read morebusinesses. Ryan was quite patient with me as he allowed me to test out the 3 different infotainment systems. After trying them all out, I choose one and was quoted at $923.74 and had to wait a week to get it installed since this is a popular place. The other place I consulted didn't even let me choose what infotainment system I wanted and quoted me at $100 higher than this place. They were able to install it in about 2 hours. The only real issue I've seen with it is that it has more glares than the original system that was in there.

    The technician created a basic workaround to get my DS18 BTC-Five Bluetooth receiver working via…read moreaux, but the setup was incomplete and poorly wired. After the install: I lost power to my 12V lighter socket, so I couldn't charge my phone. He mostly likely tapped into the same circuit as the lighter socket, causing power loss (Yeah. He didn't warn me about that before the install!) The audio was also making intermittent Bluetooth pairing failures. I would be driving and then music would stop and start again. Bluetooth phone calls stopped working--only music streamed. The install skipped key components I provided, including the fuse tap, LOC, and amp integration What I learned--and what others should know: The 3.5mm aux jack on the BTC-Five is audio-only and doesn't support calls To restore full functionality, the fuse tap must be moved to a different ACC slot so the lighter circuit isn't interrupted. For Bluetooth calls, you need to use the BTC-Five's RCA outputs and route them through a head unit or amp that supports hands-free calling. If I had known all this upfront, I probably would've skipped the install entirely and just kept using my regular USB-C to 3.5mm Audio Aux Cable Adapter. It was simpler, reliable, and didn't disable anything in my car. No wonder the guy had a weird vibe! I would have given them 5 stars if they had wired correctly, but the job was rushed and sloppy. He didn't create a solution. He created a problem! Now I'm going to have to get my brother to help me fix this. He said the tech most likely installed the tap with only one fuse (for the BTC-Five). Or inserted it backwards, cutting off power to the original circuit. Or used a single-slot tap, which reroutes power entirely to the new device. This experience taught me how to reclaim my install and turn shortcuts into teachable upgrades. If you're integrating amps or planning full audio control, skip the aux hack and wire it properly. I wasn't impressed with this install. What a total waste of money!!!!!!

    Pro Guard Auto is one of those shops that gives me that old-school LA car audio and tint shop vibe,…read morethe kind of place that actually specializes in this stuff, and there really aren't many shops like it in Arizona anymore. Jon has always taken great care of me. He's done my tint, installed speakers, added sound-deadening material inside the doors to help keep road and outside noise out, and even fixed wiring that someone had messed up before I bought the car. One of the biggest things I appreciate is the quality of his wiring. No hacking things together, no sloppy splices, and no shortcuts. Everything is clean, properly routed, and installed the way it should be. Even the work you'll never see looks good, which says a lot about the pride he takes in what he does. The value is also excellent. His pricing is fair for the quality of work you're getting, and I've never felt like he was trying to upsell me or get me to spend money on something I didn't need. You're paying for someone who actually knows what he's doing and takes the time to do it correctly the first time. Jon is also extremely knowledgeable and always willing to answer questions or give recommendations. It's getting harder to find true tint and car audio shops with this combination of knowledge, craftsmanship, honesty, and value, especially in Arizona. If you need tint, stereo/audio work, sound deadening, wiring, or automotive electronics, take it to Jon at Pro Guard Auto. This is exactly the kind of local shop worth supporting.

    I had a new stereo installed in my car by someone I knew. The unit was designed specifically for my…read morevehicle and included Bluetooth, GPS, and a backup camera. Unfortunately, after the installation, I discovered that most of it wasn't working correctly. The backup camera wasn't connected at all, and when I reached out for help, the installer stopped responding. At that point, I was out the money I had paid--including a tip--and had to find someone else to fix it before moving across the country. One of the main reasons I purchased this system was for safety during my cross-country drive. Since the Bluetooth phone connection wasn't working, I was forced to hold my phone against my chest under my seatbelt while driving--not safe and certainly not legal. To make matters worse, several installers refused to even look at my Android-based unit. They told me those systems are usually installed incorrectly and rarely work properly. Thankfully, they were wrong. I took my car to Custom Car Concepts, and from the moment I arrived, the experience was completely different. Mike got me in right away, properly installed the backup camera, and made sure everything else was working exactly as it should. Did I have to pay to have it fixed? Of course. But the price was more than reasonable, and the work was completed quickly and professionally. To say I was impressed--and relieved--would be an understatement. This is absolutely the place to go if you need car audio or electronics work done correctly. I can't thank Mike and the team enough for helping me out when I really needed it.
