Just noticed that the coloured guide lines - those that move to indicate the path of travel when in reverse - are no longer being displayed in the infotainment screen. This started just after I was going thru the menu system looking for a way to permentaly disable Lane Assist.

Any suggestions on how I can restore them?

Irony is with my partners 2016 VW Passat the reverse camera also failed recently - and it also incorporates the boot release and rear radar smarts. Been quoted A$3,100 by the dealer to fix!

FYI I am sure this was NOT caused by a solar flare.

Thanks to the anonomous reply. Started the engine then held down the power button on the infotainment system to turn it off.

Went for a 20 minute drive.

Then hit the info on/off button again = result was full function restored.

Super!
