Enabling and disabling a same topo map with two different typs on a device

[sergio2]

Hi,

I have two versions of Topo France Pro v3 with two different typs. When I put both in my Montana, only original typ version is displayed, the second map doesn't appear.
Is there a way to make appear both maps and to enable the one while disabling the other ?

GPS cant display 2 different maps but having the same FID ,as I know, you should try to use GmapTool v0.8.11, it added option to change FID in MPS subfile and change map name
