I have a TomTom Rider 2 with the 2 GB card. I have downloaded the various Map Zones for Western & Central Europe (860.3100), patched the Navcore (version 7.901) and generated the relevant .dct file for the first map (East). When I switch on the TomTom all I get is the No Maps Found message.
Any help would be much appreciated - what I really want to do is get a set of SD cards with each zone on so that I can easily switch while travelling between countries.
Yep, have just wiped the card and re-installed everything, patched the NavCore and regenerated the meta file. All works now!! Only thing is that TomTom Home doesn't say I have the latest version of the map, just 'no information available', but it does for the West and East.
