Can anyone help please. I have updated my go 550 live and out a new map on an sd card, which is patched and all works. When i try to update the map it wont allow it. looking at the preerences as it only allows changes made by Tomtom not many users. when i go into tomtom home, mapshare preferences, the slider does not move nor can i select anything (see attached) if it is a incorrect entry in the files, which one please do i change and to what.
if i revert back to my old map on the device, it updates the old map fine.
Any ideas please.
I have UK & ROI 860.3123, Nav 9.160.
Many thanks
