No radio, Cd changer but sat nav works....BMw tech cant help??

[d6moff]

Please can anyone help, im just back from my BMW tech and he is clueless..?

The problem started after my battery was removed for charging, once it was re-installed I had power to my radio/cd changer stereo controls, my sat nav works but with no sound?

I have checked the fuse in the golve box and the two in the boot...they seem fine, are there any others?? I have have a quick look in the radio module and that looks fine....nice and dry no water ingress

My ipod interface that comes from my CD changer had power as it will charge my ipod it just wont allow it to play as there is no power to the stereo/radio controls?

When I am driving the sat nav screen does blink briefly now and then......?

Can anyone please offer any advice as a car without a sound system is very dull......I have disconnected and re-conntected the battery terminals since then and no joy....

As I have just mentioned in a previous thread, my X5 suffered a malfunction of the electrical system and the first electrical unit to be shut down is the radio/cd changer. This is done to insure that the remaining electrical power available is used to keep the engine running. Your BMW tech should check the whole electrical system not just the battery to see if some components have failed like it did on my X5.

Good luck.

I believe, I had this happen to me before while I was connecting my bluetooth. Try rebooting iDrive. Just push both eject buttons (DVD and CD) and the volume knob (a.k.a the mute button) at the same time.
