Scanned the car and I have the faults - Navigation not registered and CAN Gateway incorrectly coded.

Any ideas ?

Tick / untick 'Navigation' in '19 - CAN Gateway' instalation list.

Have you just fitted or removed a Columbus or Amundsen?

Recently fitted a Nexus sat-nav. Got a feeling the Can Bus error was there before. I'll have a tinker !

I'm not familiar with the Nexus (is it OE?) but suspect the errors origin is related to the change of headunit(s).

Clear the codes and see if they come back.

Try unticking the 'Navigation' option in the instalation list (if it's ticked and the Nexus is not OE).

I believe the nexus is oe and was the predecessor to the Columbus.

Might be a conflict between the Nexus and the CAN system? Only a random thought..,

Nexus is the original sat-nav , DVD based. Selected Nav in CAN - Gateway and all is good !! Thanks a million.

No problem.

Glad it was a simple fix for you.
