Probably that although it has nice road maps on which will show a position on the street, its not really geared up to be used for aviation.
I might be confusing everyone here? I was talking about using a tomtom gps reciever, not the tomtom roadmap software. Of course I could be confusing myself, which is not at all unusual
but I can't see how the gps reciever knows the difference between roads and any other track (ie a line on a nav chart) Don't all gps recievers just cross ref from sattalites to give position? ... So tomtom gps reciever, and ipaq PDA + what memory map software to use with CAA chart?
Thanks ..... SS
