Downunder35m, that did the trick.
I removed my SD card with the maps on, delete everything on the tomtom internal memory, connected to tomtom home and allowed it to update the navecore to 9.401. Patched navcore with FastActivate_04.02.2012_Premium_edition_v1.8.8.1. Put SD card back in and maps are now available. Now doing a backup of tomtom internal memory then going to install Navcore 9.401 Fan Edition, works on 32mb models too :D
Thanks everyone for their help, great forum keep up the good work
