Hi, Not sure if this the section I need to post this to. I need help. I'm trying to update the maps in a Garmin 50LM. I used Webupdater to put Ver 4 in. Then switched to Garmin Express to do the maps. It starts to update. Says preparing your device then just sets there. Never gets to the maps. When I first started this it asked if I wanted to load to the SD card and I said yes and used a formatted card. I've upgraded the maps in this before with no problems. Now when it's turned on it says no detailed maps. It's like its lost everything. Thanks, Jim
