Please help, the past six months, my 2009 Maxima Navigation screen has been shutting down, first it flickers the Nissan logo, then I get a bluish / green screen and then black and at the same time my air conditioner kicks on. I have no control over it when this happens. after a couple of minutes to an hour or so , e radio and cd player comes back on and everything is operating fine. I have taken it in several times and they could not find anything wrong. I have a after market amp that I have disconnected and it still happens, also I have changed all my fuses and check the alternator wires for possible damage. I have been told that the air conditioner control module amplifier or the control unit can do this Nissan claims no way of scanning these units just replace and see what happens and either of the m can run in access of 1000.00, what to do?
