Thread: Why is 'Suppmap1' in Nuvi 1xxx Inventory? & Why are some maps unselectable named as 'gmapoem'?

About the >4GB image...

I think I have read that there is a limitation of the size of an image. (OM of cgpsmapper? can't remember now) It is not possible an image to be more than 4GB. But I am not sure as I think this is also dependable on the type of the image (non NT or NT image). Also this is dependable for a model - for example GM XT, nuvi 300 don't support images more than 2GB.

About the selectability of gmappoem maps...

Think this is also dependable on the type of image (non NT or NT). Maybe there could be some additional information in the header that determines should an image be selectable or static. But who really cares despite developers?
