hi to all.
today start a very strange thing about my cars audio.
sorry for bad english but i try to explain
so, i have BMW e61, which is connected to my iphone 3gs, but today when i drive and my boy was felt asleep, then i switched off bluetooth on iphone off, because i was worried about if someone calls the can be a trouble.
but when i switched off bluetooth off, then car radio switches off, then on for a while, then off. when its off then none button work on idrive, i mean menu button nad idrive knob.
also what i find that i service menu i cant switch bluetooth on or off.
what can i do? oir what is possible cause.
thank for Your reply and suggestions

 

Try resetting the iDrive - simultaneously press and hold down the volume control button, CD eject button and DVD eject button until the iDrive screen goes blank.

 

ok. i try it tommorow

 

at morning all seems ok, but before strating the engine Idrive show an error with big battery discharge rate.
maybe something stays switched on, or maybe some control unit stays on, however i wait for one guy , then we try to reset all units by removing battery wire.
