I'm having problems unlocking - or rather getting my installed maps to display (in detail) In Roadtrip. I long since misplaced my original disc and no longer have the computer I originally used to install the maps on since recently switching to Mac (hence using roadtrip) but still have all my unlock codes etc.. filed away. I have US basemap installed which seems to be getting recognised in roadtrip although again not showing minor roads and POI's etc.. and also City Nav Europe on the SD card. If In Roadtrip I Use the option 'edit Unlock codes' and add my unlock code manually it displays 'Map product not installed'. If I choose the 'unlock online' option and enter in my serial number and coupon code etc.. I hit the retrieve unlock button and I get the message 'successfully retrieved unlocks' but it doesent display anything else - if indeed it is even meant to? No other maps are dispalyed to choose in the drop down map menu other than the US base map. How can I get roadtrip to recognise and display my installed maps?
