I currently have a Mk1 RNS-E unit which has a faulty drive (I've reaplced the laser, still dead ) and the FM has stopped too....
I want to just replace it with the Mk2 LED version.
Does the coding of my Mk1 stay with the car, or the unit?
If I plug in another RNS-E, will it pick up the coding the car had set, or will it be 'reset' and I'll need to get the new unit coded?
If I need it coding... anyone in North London, or near Gatwick, who has VCDS and fancies a quick coding for a cup of tea?
