TomTom Navigator 3

Hi, I've just bought a dell axim x5 off ebay and its got tomtom navigator 3 with it. Whenthe pda is turned on and look through the programes on it it seems that it isnt loaded. I have the tomtom discs and have tried to load them onto my laptop. I select run programe and language, then it goes straight to a setup page and says " No applications were found for the devices supported by your PC " Has any body got any ides ?? This is my first PDA so I'm not to clued up. I've taken out the SD card and have had a look, it says there maps loaded on as a file. I have also connected the PDA to the laptop. If anybody could point me in the right direction it would be greatly appreciated. Thanks

Load activesync onto your PC. Then connect your PDA and create a sync partnership so your PC and PDA can see each other.

Then re-run the tomtom setup starting with disk 1.
