I read the POI installation information here and on TT. I set sail and fell at the hurdle of community. On my "Drive" program that word takes one to a forum and no where else.

So utterly frustrated after wasting an hour or more I phoned TT up. I taled to a lady with a slightly difficult accent who seemed to be in the Phillipines. However she sorted me out and the crux is it is not the Drive program that is the place to be it is quite another one and the main clue is the map. If you are not seeing a map yhou won't get anywhere. The link is this: TomTom MyDrive

There is a drop down menu on the left with 6 tabs. Click "My Places" then on POI files and you are in business.

I hope it may save you from some teeth grinding.
