Thread: How to install multiple maps on Garmin the easy way

I sent the maps to the gps and i found that the maps are compiled as one file.
I.E:
slovakia + hungary = 53,1MB (as one file)
individual files :
slovakia = 22,8 MB
hungary = 30,3 MB

Output from MapSource is always one file (gmapsupp.img)
That is the way to combine different MapSource products (or parts) in one map for device.

Where is problem?
