I had my GO720 for 2 years and it gave up the ghost. I obtained a new GO730 replacement and hooked it to the same computer containing TomTom Home used to backup the 720. I pick the option to Restore My Device and get an error that No Backup exists. Is there any way for me to salvage the work I've done on for the 720. I had Favorites saved and downloaded numerous POI files?
You're probably in good shape, but none of us recommend Home for backups. The files you need are stored in the map folder of your backup.
On your PC, look in My Documents/TomTom/Home/Backups/GO/Backup01
There, you'll find your map folder called North_America_2GB.
In that folder, you'll find any custom POI files you have created as *.OV2 files, and perhaps associated *.BMP files (the icons that match). Copy these to your North American map folder on your 730 using a normal Windows copy.
In this same folder, you'll find a file called mapsettings.cfg. Copy that to your North American map folder on your 730. IF this causes a problem with rebooting of your unit, use Home to Operate My Go and add a new favorite and save. That should resolve that, if it occurs.
