Installation on a GPS:

Copy the Garmin folder with the file gmapsupp.img 
on a micro SD card or the internal memory card from the GPS.

On newer GPS units the gmapsupp.img file 
can be renamed *.img in order to install more mapsets on the memory card.
On older units this file has to be named gmapsupp.img.

Installing on micro SD card is recommended 
to avoid booting problems in case of map errors.
