    Default Oregon Maps

    It is poorly documented by Garmin but you can have multiple maps in the "Garmin" folder on your microSD card as long as they end in .img. You can have up to 4GB of maps. They will all show up and you can enable/disable them as required via the Setup/Maps function.

    This is certainly far easier than removing the microSD card every time you need to change your map region. I personally found it highly confusing with all my maps named gmapsupp.img. At least now you can give them a sensible name such as USA.img etc.

    Took me a while to find that out but it's great.

    On Oregon you can use any file name with extension .img.
    Thanks, Kanopus

    On my Oregon 450 there is a limitation of 22 .img files. When I put more then 22 files on the SD card, the latest added maps will not show in the maplist. A solution is to merge the maps. The limitation really seems to be the amount of files, I constantly stay within the 4000 segment limitation.

    Can anyone reproduce this?

    Trying to add maps to my Oregon 450.
    Is it possible to add maps to it without using Mapsource??!? Just drag and drop?

    sure ,if you use .unl file it must have the same name :anyname.img + anyname.unl
    but if you have one of the latest firmwares and a map with FID greater than 2200 it wont work coz you dont have .gma file-
    Use Fast IMG Unlocker in that case
