I drove a Chrysler Pacifica recently that had a NAV system - which appears to be very similar to the Commander's NAV - obviously the software was done by the same company as most of the features are identical. However, they had one feature that was fantastic that we don't have - you can enter a destination by phone number! MUCH quicker than entering the address! I hope that we get a software update to allow this.. If anyone has any info, it would be appreciated..
