The biggest gripe I have is not being able to see many street names. That's the whole point of having a map! It's a shame, as people have said, the screen is really nice. 10x nicer than the one in my 03 Infiniti. Unfortunately, less street names show up on the BMW, so its a bit of a waste.

As far as navigating and accuracy, so far it's been okay, but I tried any small cities or rural areas yet.
