Command APS NTG 4.5/4.7 upgrade or update
I have a recently purchase R197 2012 and would like to know:
1) How/where (other than $350 at the dealer) I can update (by at least 10 years) the navigation maps; and
2) Are there good upgrades to the Command unit itself?
Thanks in advance for any advice based on actual experience.
Best to all, BillyD
