Does anyone ever experience issues with their Navigation not being recognized by iDrive when they start up their trucks? This is my 4th BMW with iDrive and I haven't had this issue before with any of them and the Nav system.

Basically, when I turn the car on, the Trip Computer comes on, on the right side of the screen. I have it set to default to the Direction of Travel feature when the car comes on. When the Trip Computer shows up, I know the Nav isn't working. When I click the knob, the other Nav Features aren't available (they're not highlighted). I have to eject the Nav disc and reinsert and it comes back on. It's really bizarre. I'm thinking it's the Nav disc, but was curious if anyone has had this issue before. I hope it's not the laser reader on the DVD system. That will be annoying.

I'm going to try the Nav disc from my M5 and see if that works, but it's not all the time. It happens maybe once every 15 times, if that. It's totally random.

Just curious if anyone else has experienced this?
