As it's starting to get cooler and wetter, are you leaving the A/C on? It de-humidifies the air in the cabin, without it you will get electrical gremlins all over the place, but this generally starts in the switchgear as they use microswitches. Then multiplug connections will start to fur up and go green causing other problems.

Sorry I cant give you a definitive answer.

Oh and be careful pulling power to the nav unit, if the red light is on (on the main box in the boot) and you pull the power it will crash irrecoverably.
