I was wondering if any of the .netters know of any good local audio shops here in So Cal.... I'm really looking forward to get an aftermarket headunit installed. The problem is that my car has stock navigation and I still want to use it. I came across the post by TeckIS300 but never planned on doing it myself because I know nothing about audio or what so ever. I've also heard tons of negative feed back about stores like BestBuy and how the techs don't know jack s**t there. I live in the Riverside area and I'm having a bit of trouble trying to find a local shop..
