7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

iDrive freezes after 20~30mins of driving

I dont know whats happening. It started from minor and not very frequent occasional distortion sounds from the speakers intermittently. That was a couple of months ago.

Now few days back i plugged the 3.5mm jack to my phone (i have modded the radio module to get the wire out for the phone) to listen to some music. It worked fine for 20mins while driving and then these crazy distortion noise started coming from the speakers and the iDrive screen froze.

The wheel to control iDrive features started spinning freely with screen still frozen whenever i tried to get it work. iDrive starts working fine after the car remains locked for 20mins or more and computers reboot and refresh until next time i start the car. But again it doesnt takes longer now than 30 mins after which i end up with a stupid 'paused' screen.

What is happening? Is it the wire that was used to mod the radio for the 3.5mm jack for the phone? But if the wire is bad, why does it works for at least 20mins before iDrive goes kaput again.

Also the CD changer starts switching CDs on its own while this problem happens.

Help please.
