I was told by damon the map parts were no longer available because the contracts did not get renewed....this was in 2009, I since use a garmin
and pull up where we are going using my trucks nav system then make notes for points of interest....
someday i will find a great nav for the rv that doesn't cost 2 arms and a leg
would be nice to pop my trucks systme in the rv.....
