Thankyou Mike for those suggestions. Will give those a go. The wincepatch was basically a file I bough which is a patch for my WinCE to add a different user interface into my car unit to make it look more iphone style.

Will update with results! Thanks again.

I can't seem to find a sys.txt file. I have found a sys file which is just in the Primo folder on its own which says (Along with a lot of other stuff!):
[gps]
port=7
baud=57600
source="nmea"
I will rename that and see what happens. Can't find a save folder either yet. Did say I was a newby...
