GPS for the HP Jornada 928

can someone let mek know what GPS unit i need for this phone is it possible just to get UK map software?

Best bet is the Tomtom Kit and Jornada Connecting Cable. http://www.totalpda.co.uk/product4168_302.aspx
The kit gives you a GPS receiver that will plug into the base of the 928 with the connecting lead being a Y shaped cable, also charging the receiver & PDA from the cigarette adapter in the car. This leave the CF slot free for a memory card to Load the UK Tomtom Maps onto, (which also comes included in the kit!)
If you have any further questions, don't hesitate to contact me!
