hi biggerdave - thxs for the suggestion. let me ask: with garmin, i would be able to have unlocked maps and load the maps map by map into the device. does tomtom have the same function ? i know that i can buy individual maps from tomtom. are there unlocked maps around and can i upload several unlocked maps into the device or would i nly be able to feed one map on one sd card into a device if it has a card slot ? ...
