Generally all Sat nav's do the same thing... i.e get you from A to B without to much hassle. To sieve out the good from the bad tho' there are a few things to look for.
1. Battery life
2. Processor speed (required for quick recalculation and instruction)
3. Satellite chipset (surf star III or similar). How quickly it logs onto a satellite. The TomTom 10 series uses 5 satellites. I believe earlier versions used 3. Using more does not make them more accurate just gives em more of a chance of a fix all the time.
4. Ease of use. Some give better spoken instructions like "Take the motorway" rather than "Take the next left" and some do "Take the M11 motorway!)
These are the basics but there's a lot more if you require them like bluetooth hands free,Speed cameras,Traffic congestion, calculation of routes,Navpix as on the Navman and how easy it is to set all your parameters for a journey.
You really need to read some reviews or go to some stores for a demonstration of what they can do.
