I am looking for help in knowing how to integrate a bluetooth module into my factory stereo unit (Bose Symphony). I have seen a lot of dicussion threads, but can't find one with instructions (for dummies!) for a successful install and integration (including automatic muting, use of in-car mic, etc.).

Appreciate all opinions/recommendations on specific units.

Also, how can I be sure that my car is pre-fitted for this integration?

Thanks for your help...
