BBC is installing...
the ME3, XM, Dietz 1417/1380, Ampl TV antenna and the factory submarine antenna which he CORRECTLY integrated into the diversity system. He's also VAG'd everything to my Euro RNS-E and Phatnoise. You are correct. Some Audi techs run from these jobs. All I have to say is; stop by and look at the ABSOLUTELY SEEMLESS install in my Audi. I'll recommend him. I installed my RNS-e (to save $$) and unknowingly broke a pin in the harness, losing my Phatnoise. BBC caught the issue right away and got the Pbox working again.
Don't pay to have someone learn how to do the install it on your car. Pay once and be satisfied. Don't get a great deal, have issues, bring it back and hope they know what's wrong with it. I don't know of anyone else’s install jobs (in Orange County) simply because I have not seen their work/feedback posted. PM me if you have any other questions. I'm in Dana Point.
