TomTom One v1
Boot = 5.5130
System = 8.417 (SE I think ?)
Maps = UK 860.3101 - From UK 845.2667
Installed new maps 860.3101 as they seemed to be most compatible (extra features etc) all appears working on the TomTom - found my Favorites were not present - copied over Mapsettings.cfg and got into the reboot problem - found a solution, connect to TomTom Homw and add a Favorite - downloaded new TomTom Home ...
