I've had my Corsa since July last year. Last night on my drive home I noticed the satnav was showing my location as around 2 miles away from where I actually was. I hoped whatever it was would be gone today, but wherever I go, it makes a paralel trip about 2 miles away from where I actually am. Has anyone come across this? By the way, by satnav I mean the car's infotainment system. Any help would be most appreciated as I'm due to go on a trip in a couple of weeks' time and really need this solved by then! Thank you.
