Maps not showing up on PDA

Hi everyone,

I have just got myself a PDA running windows mobile 6, and have got my
navigator 6 up and running.

I wanted to get some of my tomtom maps which i had purchased for my tomtom
go model onto the PDA.

I have managed to get my western europe map working, and my USA one, but i
cannot seem to get my Australia map to show up at all ( as in im not even
getting as far as putting in my activation code. )

I have tried to copy / delete and copy it back onto the memory card again
but nothing, it will not show up under manage maps.

Anyone got any ideas - i might be missing something off the tomtom go?

Thanks
