04Z4 No sound from rear speakers
I have posted this in the Z forum but thought it was worth picking peoples brains in the general BMW population.............
I have the business radio in my 2004 Z4 3.0 convertible
When I bought the car the amp was missing so I bought a new factory unit from a well known online supplier.
The unit is the correct one for my car but there is no sound from the rear speakers only the front.The fade is set in the middle and all other functions operate as intended.
This may sound stupid but would having the ECU removed(it is out getting flashed for the S/C)
have anything to do with it. Can anyone shed light on this please.
