If you purchased a map within the past 24 hours from TomTom then you are likely to see an error message when trying to select the map: “You cannot use this map on this device.” Turns out there is a problem with the certificate on the map and you will need to call TomTom support (US: +1.866.486.6866) to have them generate a new certificate, unless you downloaded it prior to 2010/8/18 3:19pm EDT then you will need to delete the map from your device and the cached downloaded files for the map. Updating your TomTom from the Home program should install a fresh (and fixed) copy of the map.

On a Mac OS X system, the following steps are necessary to remove the map:

1. Connect the TomTom to the computer
2. Open the Internal drive
3. Delete the folder containing the maps – mine was titled North_America_2GB
4. On the Mac, in your Documents folder, remove the contents of the folder TomTom/Downloads.
5. Using the TomTom Home program, update the device and install the map.
