Hi gbdoc,

the trouble is, Adrian is having a Nav3 device and needs the myTomTom support application. Therefore there aren't that much files resting on the computer. But having a look in the folders to see which data gets deleted is quite worth thinking about. It'd be good to save POIs and favourites that have been saved from the device.

But all other data as application remnants remaining in the cache folder or map remnants of broken downloads I recommend to just delete as those files won't help at all. With the newer devices all data gets stored on TT's servers and not really on your local hard disk drive except for caching during the installation.

Also keeping a map if one get's another device as a replacement won't help as the maps are linked to the s/n of the device and you won't be able to use your old map with another device even it's the same model.

It also might be that removing the myTT application isn't necessary but using that way you'd make sure that there are no old files remaining forcing the updates to hickup and thereby fail again.

Regards

Lars.
