...and it's been going on for months..
i have successfully (almost) installed bluetooth in my e46.
it works fine except for the fact that the sound quality is awful.
this is because it uses the internal bluetooth module amp and nothing else to provide sound.
its thin, distorted and too quiet.
the reason for this is because it does not get pumped through an oem HU...i have installed an aftermarket HU (Alpine CDA 9856R)
the bluetooth audio goes straight into the aftermarket morel speakers via a telemute
this is a wiring diagram of what ive got
i have also installed an aftermarket amp.
i have tried everything i can think of but cannot get the bluetooth module sound through the aftermarket amp
any advice or suggestions greatly appreciated guys
