This is really a ZERO, like other reports since 2019 til 2022. I was customer for a long time, but when I my brought my BMW in, mid July 2022, my system was working. Delays kept coming on parts.I was getting both bumpers repair. I was told I was getting a new bumper but got there it was my old bumper,patched up. The company never told me, I had to look at my car. I waited to get my new bumper. I had to call abt my car & when I got my car back, the system wasn't working, plus cover inside my back was broken. During the time they had my car,when it was supposed ready, there was no call.I passed by shop to see my trunk up.(wondering why it's up) I have a new battery, I don't need a boost when Im driving my at all. They state my amplifier had it course. I took it to the BMW place, early in the morning, they said that's McDaniels is incorrect, water had got on it & messed up my speakers. I spoke with the owner. (going back and forth) He's talking abt the sound was so loud it hurt his ears & making like the amplifier failed. The speakers sound is not loud after water/ moisture got on the amplifier. They assume bc I had a old amp in my car, which my sister gave me it as a birthday present for my old car. BMW have good amplifiers. This happened at the shop, NOT BEFORE I BOUGHT IT IN. Im just clueless about my car, when I picked it up, and they passed me my keys. The insurance company stated McDaniels supposed to do a walk around but didn't. read more
