will do that when I feel like I need a new one anyway. The Garmin  
flash process is not very stable and had already troubles 2 times.  
Once the unit was exchanged under warranty and 2nd time I could fix it  
with the download version instead the webupdater.

to sad they don't and we are offering so much for free with OSM
