HI, having a problem with my sat nav unit in the focus, i think it the CD Navigation unit not the posh touch screen, suddnely saying no gps signal and therefore cannot tell where it is or how to get anywhere. had a look behind the unit, all connections look ok, cant see any break in the GPs antenna as far as i can see it. where oes the antenna go after leaving the behind the dash/gps unit? any ideas on what i can do to get it working again. thansk for any help Tony
