I agree the nav is a major improvement and of course there are things that still need work. I haven't seen a system yet that is perfect. I only spent a week and a half with my '09 iDrive when I did European Delivery but here is what I know regarding your comments.
- Haven't tried importing yet so don't know.
- If you have the Aux audio input screen up hit the Options button and you should be able to check the box for Random that will shuffle your iPod songs.
- Don't recall any problem with the white line on gray background.
- If navigation screen is up on screen, hit Options button, select settings, and you should see a box to check for 3D for Perspective view. (sequence from memory but its in there for sure)
- Didn't have problems entering European addresses but haven't tried with US yet.
- Never had problem double selecting numbers.
- No faults.
- I used the steering wheel button or dash button to change radio stations and the station name was still displayed on the nav map. These buttons cycled through all the stations it could receive. I do wish though that the song information was displayed somewhere.
