Encountered some difficulties updating my maps through Latest Map Guarantee. TomTom HOME got through downloading the North America maps (it took several hours), but then always got an error message for Western Europe etc.
I gave up on the Western Europe maps, and installed North America using the regular update maps section of HOME. This worked okay at first. But my settings and favorites were missing, so I manually dragged my backup copy of the mapsettings file onto the right place on the TomTom. Now the device goes into an endless loop when starting up, so I'll have to restore the backup using either TomTom HOME or my manual backup.
Once I'm back to square one, I'm wondering whether it might not be better to just manually install the new map files by dragging them. Is this possible (and which files to use?), or do you have to use TomTom HOME to install maps?
1. Make a complete Explorer, not Home, backup of your unit's contents. Ensure hidden files/folders are showing.
2. Different operating system may store the Tomtom Home folder in different locations so you may have to hunt for it. But for XP's go to the location of your downloaded map. you'll find it in this location:
C:\Documents and Settings\yourname\My Documents \ TomTom\HOME\Downloads\complete\ map\ your_map_name
(Substitute your specific map name every time you see your_map_name in these instructions.
It's a cab (compressed) file.
3. Within the compressed cab file, if you look at the contents, you should see a your_map_name.zip file, perhaps a couple of .gif files, a your_map_name.toc file and, importantly, an activation_map.cab file.
4. Use Winrar or some other archiving program that can unpack .cab files and extract the contents of the your_map_name.zip file into the current your_map_name map folder on your unit. If you don't have a folder called your_map_name, then create one using Explorer.
5. Then, extract the file in the activation.cab file into the same your_map_name map folder on your unit. If you see a .TLV file, it should go into a folder called 'map' (no quotes) on your unit.
6. Make another Explorer backup of the unit's contents to a different folder on your computer.
7. Disconnect the unit PROPERLY from the computer using the Safely Disconnect icon in your notification area of your desktop.
