Garmin Montana 600

[jaybey]

I need some assistance please!  I have a brand new Garmin Montana 600 and I run Windows 7 on my PC with both BaseCamp and Map Source.  When I try to load Arizona Topo and SW US 24K they wipe each other out if I load them indivdually but if I load them seperately they overlay each other.  So far my best answer has been to load one on the micro SD care and the other on the Montana.  Is there anyother way get them both on the SD card without deleting one of the other?  I have both on my Nuvi 760 running seperately without any issues.

Both programs send the map data as a file named /gmapsupp.img.  Rename that file to somename.img (.img extension required) before sending data from another mapset.
This is step 8 (repeat steps 2-7) in the sutorial: http://gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/

I believe MapInstall is pretty smart and will name the IMG file by the name of the mapset if the GPSR can handle multiple IMG files.

that's how it works on a Mac when you have your Gps connected, I think the Windows version has caught up.

Thanks for the replies.

I did a file search on both the Garmin and the SSD card and neither have anything like gmapsupp.img. They dos seem to work alright on the surface but I will need to take the Montana out for a field trip and see what gives.

One of your points is "they overlay each other".  You can turn different maps on and off in the settings of the GPS.
