hi all, im trying to gather some info on how difficult it is to fit sat nav into a golf that originally didnt have it fitted. i would want to fit a genuine vw unit which i gather to be a rns510 but there seems to be many different models which only run on certain gateways etc and also if you fit the wrong version you can get battery drain
what parts would be needed? obviously the unit and gps aeriel. anything else?
thanks in advance for any help
Andy
