if anyone has a problem with sat nav on a solar reflective windscreen it might be worth knowing that the black bit on the windscreen beside the rear view mirror is not affected by solar control so you should get a fix if you can mount the sat nav there. Rayjay120
had this message a few times on mine but it goes away after switching the ignition off - had alarm go off in the middle of the night then when i started the vehicle in the morning i had a problem with the bonnet switch - showing bonnet open all the time.
