Hello all, Just a few things to keep I mind when upgrading from 4.x to 5.0. 1. you must remove all of your 4.x maps and pois. 2. your user pois, these are the POIs you create must be converted from 4.x to 5.0 using a converter that must be ran on a windows based PC. 3. any routes you create must be ran through a converter to convert those from 4.x to 5.0 format. Hope this helps. Chris Chris Grabowski - Customer Support and Product testing Sendero Group "The GPS company."
