I've seen the PC plans produced from both a Bluemap device (Garmin) and a C-Map device, and reckon that the C-Map is better (full Admiralty chart in .pdf format - although this was from a Hummingbird unit, not a Navman), whilst I covet a Garmin unit because I like the way the software works, I must say that the C-Map planning was better. Well I think it's C-Map. Jackeen, help me out here!
Just a thought Andy - are you very tall (or can you do impersonations/mimics of everything? - I'm thinking of Police Academy here
