I bought this based on other folks reviews, and had it professionally installed into my older Cadillac. The sound quality coming out of the speakers was great, lame that it didn't support A2DP but shame on me for not catching that- the bad part was the microphone pickup. We moved that thing all over the car to try to get something that didn't make me sound like I was calling them from a tin can in Australia, and no dice. Technology in cars has improved a ton, I don't get how neither this nor the Parrot 3100 can work worth a darn. Two thumbs down.
