Thanks to the helpful tutorials I have successfully updated my tomtom xl to navcore 9 and a new 865 map.
I'm having problems patching the tomtom home app as per the tutorial. I've let tomtom home download the new app and i get the message about the map being incompatible with my device. I quit tomtom home and run the keygen but i get the above error message. Have tried repeating and rebooting with no joy
Would be grateful for some help.
