You can in fact use TomTom Navigator 6 on a Treo 700wx and it works very well. The phone itself does not have GPS so you have to use a separate GPS receiver that will communicate with the Treo 700wx via bluetooth. So, the first thing you need to do is pair the two devices by adding a new partnership on the Treo. Once you have a partnership you need to set up Com ports on the Treo to communicate with the external GPS receiver. I have mine set at Com 0. I hope this helps!
