[OSM-newbies] Using the OSM map on Garmin

[Max Moritz Sievers]

Hi,

I downloaded the img file from 
http://wiki.openstreetmap.org/index.php/User:Computerteddy an saved it on my 
micro SD card in "Garmin/GMAPSUPP.IMG". The device sees the space which the 
map takes on the micro SD card but it doesn't show it in the selection dialog 
for using the map. I'm using a Garmin etrex Legend HCx, firmware version 
2.60. Do you have an idea what I'm doing wrong?
