I have a Tom Tom One V2 (regional) that uses the ultra sensitive SIRF III chipset (so the box says) and have no problems getting a signal in my car which has a heat reflecting windscreen. My tom tom does sometimes take up to 5 mins to lock onto a signal though, even when Im not in the car.

If you get an external antenna for it and place it on your windscreen on the black dotted areas either side of your rear view mirror, then you will be able to get a good signal as these areas are not coated with the athermic coating.

Hope this helps.
