Route 66 map update

Question

Hi I have bought a Trumpion gr1 sat nav which runs Route66 map software. the map requires updating appereantly you can go onto their website and download it but I have tried 5 times and can't find it anywhere... trumpion claim it costs £15.00 for the update but it seems to be well hidden! any help or advice would be most welcome or a link to the download..... their maps are well out of date even although this unit is 3 days pld the maps are about 18 months out of date!
