Hey all, newbie here. I own a 2018 Golf RLine. It's my second Golf, the first being a 2005 Golf (so long ago now). Hoping to finds some answers on the forum.

I have a factory installed Columbus in my MY2011 Octavia. The satnav has suddenly gone mad. The map tells me I am about 2 km from where I really am. And the compass has me facing about 90 degrees different from reality.

The audio/radio etc all seem to behave as normal.
