help please

First off many thanks in advance. I have a Dell Axim with tomtom navigator, which i think is version 3. Everything has worked fine up till now, it is not bluetooth it is connected to the reciever by a cable. Now when ever I try to use it I get a message saying gps disabled, no idea what I have done but I can't seem to put it right, any help greatly appreciated.

Welcome to our forums.
Reset your DELL then load TomTom and go into GPS Status (tap on the screen then tap MORE) then tap on the GPS tab and tell us what settings you have selected.
