We have just bought a go 620 professional for our Motorhome. \n\nHad issues setting the vehicle dimensions. \n\nThen it refused to recognise our wireless some 18" from the router! The wifi was working as well as it can given our less than stellar BB at 5meg. \n\nThis morning it says it was connected to the wifi so great on we go with updating. "Update failed " after an hour it had crawled to 9%\n\nIt now is insisting we install a map of europe! It was showing the UK fine yesterday so ??????????????\n\nIs this thing scrambled or is there a factory reset or is it just pure bad luck? What ever got to say far from being impressed.
