Hi (from the UK) any one have some thoughts on why the lights on my 2015 Rad Rover just power down after a few seconds of illumination?  Never doen this before and it's one of the functions that has never failed - to date!  The screen stays illuminated as well as the 'lights-on' logo though the lights just go off after 20 seconds or so.  Turn them off (double button push) then back on and they are restored then a few seconds later they're off again.

A very annoying mistery and any suggetions welcome, thenks...
