I am not happy with my stereo in my 911. I am keeping the factory original just incase but I want to be able to put t a nice system in.
I went to Circuit City, Best Buy, and some local shops to look what they have and how "experienced" their technicians are. When I look at the guys who install stereos in any of those places, I don't know if I want them to touch my car.
Would it be safe to use places like Best Buy or Circuit City or should I go to Porsche Dealer and ask their detail shop technicians to install?

Any Advise???
Thanks,
Alex.
