How long have you people been working on these receivers in our car's? 
I've had mine about 2 month's (just now had time to research) and I have already found out that the only thing that is BOSE in our car's is the speakers & speaker system set up and the amplifier.
I am now trying to find out what mazda put in our car's for a receiver.
