New M5 owner here.
Please help. I've had my 2015 M5 CP for a few days and took it into the dealer for a new tire set and on my way home the iDrive system would not connect to bluetooth neither did the navigation and then intermittently it turns off and back on constantly when stopped and driving.
I've been combing the interwebs for any possible solution suggestions before I go back to the dealer (I've emailed and left messages and haven't heard back) and get screwed again.
Too many suggestions on a fix. What should be my first troubleshoot or diy fix? Software update?
