I inherited a nuvi 360 with City Navigator North America NT 2008. Can someone help with what I need as per map. I don't have an sd card and don't want to get one if at all possible. Also if you could, what software I would need. This is just for a map update. I have seen maps with locked and UNlocked. The unlocked ones have been unlocked with a GMap tool correct? Now do I just need the map or all of the 3D, JCV, ASR ect...

Ok if no one can help me, how bout if I use the unlocked version. Do I just copy and paste into my garmin..??

you will need the map at following link, just download the unlocked version.

and you won't need 3D, JCV, ASR files since your device won't support them. if you cannot fit large size of the new updated map on your device, you will need to copy the new map to an SD card and use it in the device. cheers
