    Default Garmin- transfer maps from mapsource

    Hi, I am new on forum but found a lot of very useful information. I am most interested on information about Garmin navigation device, I have Nuvi 760.
    I still have problems with transfering maps from Mapsource to Garmin as sometime maps earlier installed on Garmin dissapear after transfer of new maps from Mapsource. Is is possible to keep all maps on Garmin and transfer each map separately from Mapsource? ALso, could anyone nhelpm and explain how to delete old maps from Mapsource.
    Even if quaestions are not so clever, help is welcome.

    Hi I have a Garmin Oregon. This device can handle all maps as long as the extension ends on .img
    Some other Garmins require only one filename: gmapsupp.img.
    So if you load from Mapsource to Garmin the file will be called gmapsupp.img. If such a file (with another map) already exists on your Garmin, it will be over written.

    I deal with this by first renaming my file on the Garmin in eg. "mapofitaly.img" before sending the 'new' file from Mapsource.
    If you do this consequently you built up a nice collection of maps ready to be used on your Garmin device.
    You need quite some storage space. My one has an extra micro SD card in it (16Gb).
