2014 Navigation Dead...Black screen of death

[c4rter4]

Hello fellow M5 owners. So I could not wait to get my car back from Germany as many of you know the pain in waiting... I have had it for only a month now and have had a few problems. First the key would not register and I had to put it up to the steering column. Then as I was driving it, the Navigation and all the electronics other then the instrument cluster went out. I read that it might be a battery, and I disconnected it but it did not work. I took it in and I guess they are replacing the entire thing.

I also told them about squeaking in the wheels and the wheel bearings were bad as well...

Just a heads up for anyone else out there.
