I've been doing a load of research. The best UK sat nav seems to be Destinator with Mapmonkey. Unfortunately I'm out of cash at the moment (summer hols etc.) and will have to make do with Autoroute 2001 with my BU-303. Is there an add ons for directional voice prompts and is there a multimedia front ends that accomodate Autoroute 2001? or any other low cost sat nav options? may be using Autoroute 2001 maps?
