Jim, unless CP11 is alot different than 10 both the dw and I believe that you will be happier with SA, we have both and she prefers
Street Atlas.
With
CoPilot 10 the rv option gives a choice of a 12'6" or 13' clearance, real handy huh?
If you have not considered getting an external receiver/antenna give it some thought, our
MR350 is some of the best money we have spent-mounting in on the top of our roof ac and routing to the interior was easy; let me know if you would like to see pics.
