Purchased a couple new mini SD cards and one new Montana.
When uploading a custom map from Mapwel in a .IMG file everything registers and goes through.
Once I turn the GPS on and Select Custom Maps to be enabled...this does not show up. gmapsupport.img is in the directory.
I put old mini SD card in and uploaded same map everything works well.
The new mini SD card is FAT32 8GB.
Took the other new mini SD card and copied everything from my old mini SD card...still can't bring up custom map.
