Okay this is the second time this has happen to me and I can't figure it out. We drove from Michigan to Kentucky last night pretty non eventful trip and our 2005 RR was a great ride down. However this morning when I went to the car I noticed that the Navi/Radio display had not powered down and was stuck on the Land Rover emblem and the power on knob/button was flashing. After several start and restarts still couldn't get it to reset. I popped the hood to disconnect the battery only to find that I didn't have the proper tools to disconnect the batter I went back in to find it powered down. Started the RR and everything was back to normal. This is the second time this has happened anyone know what is causing this and how to fix it? Thanks.
