Hi all I have recently come to appreciate just how much work has gone into producing the Sendero application. My wife has recently acquired a Tom-tom GPS for the car. The first thing to be said is that it is much more limited in its application than the Sendero. It does not have a route planning or exploring function. It can only create routes from the current position. It is very good at creating new routes if you miss a turning. The Tom-tom software also appears to do some filtering of the positional information that it receives from the satalites. For example, it never gives you a position off a road - even when you are off a road - there must be some correction mechanism that makes assumptions and always relates them back to a road. I was expecting to be out of a job for route planning when we are on holidays but Sendero can still beat the Tom-tom and help with the planning. Steve
