Je fais des recherches sur le net pour trouver eventuellement le probleme de mon autoradio est je viens de tomber sur un message posté sur un forum anglais /
Exclamation READ THIS before ordering a new CCC idrive unit - may save you a few $$$ Hey there,
I have tried to search for it but have not found it in the forum, so please excuse if its a double. Some of the CCC professional units in the e60/61 fail after a while with CCC screen going black and not starting at all - the idrive knob spinning etc etc..
The usual answer from BMW (After you´ve tried to reset the unit with the three button combo - which by the way also works when ignition is off - with comfort entry / key) that you will have to replace the unit - HOWEVER, and here it goes:
The most common problem (in Scandinavia that is) with the CCC is that the DVD drive reading unit starts to misfire, that reader problem makes the entire system unable to start - this can happen with age, or a scratchy DVD - regardless, IF you manage to get your NAV DVD out by resetting it (with the volume, and both eject buttons pressed at the same time for a few seconds) , try leaving it out - if your system stays ok, get your BMW dealer to exchange the DVD reading unit inside the drive and all is well... is a GBP 250 job overhere, probably half in the UK... May also be worth trying if you can´t get your DVD out, since the GBP 200 investment is better than a few thousand.....
Anyway, hope this helps!
En gros le gars dit que la cause la plus frequente de ce probleme est due au fait que le systeme essaye de demarrer à partir du Dvd de navigation et qu'avec le temps ( probleme de lentille ou usure du dvd , griffes etc ) celui ci rend instable le systeme .
