What vehicle?

Citroen, Peugeot, Renault and many more have windscreens that won't let the signals through. In which case you need an external GPS antenna...

Try placing the unit on the roof and see how long it takes to get a fix.

Good call but the newer Navmans have solved that problem now.I have a Citroen and it works fine.They are good for the occassional use but not if your a driver.Had a F20 for a few months now and there's some flaws with it
