Last weekend I got the SD card out and tried Merc Download Manager to update check my map version and then update it. I left it running and first attempt it foroze at 25%. I then cancelled it and tried again. A few hours later it was stuck at 35% then cancelled again, resumed and this time 52%. By this time the computer had been running all day and it was after midnight so I started again and left it running overnight. In the morning it was frozen at 92% so started again and this time froze at 95%. Eventually it got to 100% and started the install process which was very nearly 24hrs after I started. Anyhow, it's working fine and the new menu for the Nav is the same as the car menu's rather than the horrible ugly Garmin menu.
Glad I stuck with it and just wanted to share my experience in case anyone else encounters the same sticking problems.
