Tom Tom 910 map update with 920 maps?

The only other way to get maps is to look for third party map files. Sometimes they are free. I've not tried to find one for my tomtom but have for my magellan. So if someone has done one then you just need to search the web for something like tomtom map download and the area covered.

Its sounds like a problem with the screen then. If it is still under warranty, return it

That is really strange!
I can only suggest that you verify what MAPs are physically on your TomTom device by connecting it to a PC/LAPTOP and use Windows Explorer to look at your GPS drive folders: should see a folder for each 'country' (like GUAM).
The normal way to check which maps are registred and loaded on your device is to use TomTom Home -> Update maps function: it will show you the status or whereabout of any Maps that you have loaded or backup and which one can be purchased.
Hope it helps: let me know how you go.
ps.i f you wisely backup your device on a regular basis (via TomTom Home or direct copy to your PC/LAPTOP), you could always RESTORE FROM BACKUP and start again.

You can get free shared updates from the users when you install the Tom Tom Home Software, but to update the map with the TomTom approved information, you will have to pay, unfortunately. So far, the people-uploaded maps have helped me immensely, though.

suggest reload tom tom software on to memory card but format card before doing so

Sorry but unless you have access to USENET and know what you are doing then no you will have to bite the bullet.

Sorry


If you find this info useful please click

nope im afraid you will have to cough up for the new maps (map corrections etc will only show new one way directions, and new or adjusted POIs), might be a good idea to wait till brand new maps are available before you splash any cash, good luck

Your Favorites are located in the Map directory in the TomTom.
For example if your using the North American map (North_America).
In a file named MapSettings.cfg.
When you update the map and some times the application this file is overwritten.
I recommend copying the file to the root directory of the TomTom or your computer if changes are made. That way you have a easy back-up of your favorites file.

Unfortunately to recover your old file you may damage other file in the process.

I hope this helps.
