Sat Nav - another Tom Tom question

[LadyMuck]

Looking at getting a Tom Tom. There seems to be quite a large price difference between the Tom Tom One and the Tom Tom 710 for a similar product - one is slightly larger and has a longer battery life. Am i missing something?

They have different maps pre loaded I think. 710 does Europe in detail. We have te 510. Does Europe main roads.

really depends where you need it for, if its just for uk use then the tom tom one will be fine, i have the tom tom one it's fab

Thanks. As far as I can see the only thing I might miss would be the ipod comaptibility.
