hey guys!
thanks for you hard work!! i really appreciate it!

Here's the thing:
I created an image with mapinstall (Macintosh version) and copied it on the SD-card(Garmin folder). But the map doesn't show up in basecamp?!? So i made some research an nailed it down to "setting the MS (Mapsource) flag"?? with gmaptool!! is this the right solution?

gmaptool - tab WRITE - "check" set version in header - MS "0" - save with "write selected"???

thx in advance!
