[ipaq_gps_blunder]

I have a IPAQ 3630 , i have tried to get Tom Tom 5 working on it, IPAQ sees the GPS in tom tom GPS settings but they dont change from a grey state to blue and it wont work, The Screen shows at least 9 Sats but it wont sync to none of them, how can i get it working.
I have also tried Tom Tom 4 , but when it fire it up it cant see the maps, i have the Tom Tom 4 maps but where do i save them and under what format ie great-britain-map, but in which Directory/Sub directory do i save them as i am stumped .
Can any body please help me??
