Hi Spanners - thanx for your most prompt reply. It's Navigator 5 not Go and was purchased for the PDA, actually as a package that Dixons sold me (including the ipaq). There were no discs and the UK maps were on an sd card. Now, running my skull and crossbones up the mast, would anyone be so helpful as to place a copy of these discs in my possession....... errhum? Hehe!
