BaseCamp. Will download and get up to speed there. The wiki in your sig has a lot of great stuff, too. Thanks.
Is there a step-by-step 'best practice' for creating a City Nav route in BC and then successfully navigating it on the Montana? If it's in here, I missed it!
For the real funky stuff I just follow tracks, so my concern is routing the paved and dirt roads found in City Nav and having the unit follow the route I have chosen on the PC.
