Get a Garmin....

My new 07 is in now getting the BMW nav, (if you can call it that) ripped out of it and having my Garmin Nuvi custom mounted in what will be the flip top.

Not a cheap "fix" on a brand new car.
But the BMW Nav is a POS in comparison to even a low end Garmin.

If only I would have listened when the dealer told me it was a waste of money to buy....
