I have used Tom Tom Navigator on a PDA and now I have a Tom Tom One Regional which is considerably better, all sat nav systems will re route you if you miss a turning, sometimes by asking you to correct your original mistake like when on a roundabout or if you miss a turning they all re calculate another route within seconds, may I suggest you do some research on some of the sat nav forums, I think the jury will be split 50 50 between the Navman and Tom Tom as much of your opinion will be down to personal taste, as far as connection to satellites goes they are all generally the same and most use the same chipset, the function of the navman which tells you where to park is called a POI (point of interest) which can also be programmed into the Tom Tom, you can POI's for whatever you like eg: petrol garages, zoo's supermarkets etc etc. So in summary and as you have hinted I rate the new Tom Tom Regional very highly and they are currently only �199.99 in Argos.
