Another major dislike I have for the factory nav unit is that unless you also have a CD changer you can only listen to CDs if you take the nav disc out. One major concern I would have is the disc getting damaged taking it in and out while driving. Put it on the passenger sit for a second and it ends up getting scratched by accident and is unusable
As rodster mentioned, not being able to enter info while driving also really sucks but understand why.
