  Notes
 
-
GPS marked as Not tested would work without any problem but this is theoretical beacause I never tested it on my computer.

Non listed GPS are also compatible with Cartopro, but they are not implemented. That means that you have to implement there manually. You will found all explanations on the Cartopro help
