New to forum. new 2013 LR2 LUX owner but previous Evoque and current 2011 RR Sport SC owner. I have a minor navi tech issue and the dealership says "it's working fine" (ever heard that?) . So I am hoping all you experts can help out. Here is the problem: When the navi display mode is set to auto (as opposed to day or night mode) it stays in "day" mode with the back ground still in white only dimming slighty. I can switch it in night mode and the background goes dark gray as expected. My guess was some kind of bad light sensor preventing the nav from flipping to night mode when it gets dark out. But according to the brain trust (extreme sarcasm implied) at Land Rover of Chattanooga the fact that the bright white background dims alittle in auto mode means all is well. Any thoughts? Thank you in advance...
