I have downloaded and have an existing "City Navigator Singapore/ Malaysia NT 2010.20" that was working fine. I downloaded it from Garmin Singapore Website. I was told that I am NOT allowed to download updates anymore as I am only entitled to download a free map update only once and have to pay for subsequent updates thereafter. I have tried to installed this latest "City Navigator Singapore/ Malaysia NT 2010.30 Q3 (img+JCV)" into my Garmin 1460. I used Jetmouse Keygen with FID:2133 but my Garmin device could not read the map. Has anyone successfully installed this map? Is there any other configurations I need to set in Jetmouse Keygen Custom Mapset (example: FID, PID, RgnID, VenID)? Sorry, I am a noob, still finding my way around. Thanks in advance for any help I can get.
