Possible Navigation Failure

[BilboBoggins]

Hi,

My 52 S-Type has developed a problem where the screen appears to be going through a reboot cycle. The screen come on but after 5 to 10 seconds seems to reboot, the buttons do work during the short period its there ie:- the radio works, CD changer in the boot etc, the only thing that doesnt is the SatNav, just a white screen. The messages I get a glimpse of are 'Communications Failure, please contact your dealer' and if I've got the climate button selected when it boots it will say about no igntion. The reason I believe its possibly the DVD navigation unit in the rear is that it doesnt eject the disc if I press the eject button. There is power as I can hear the disc revolving. A couple of question if anybody can answer. is there a way I can bypass the Navigation unit to see if the screen stops rebooting? If I just disconnect it nothing works, and is there anybody that can check/repair the Denso Navigation unit ?

All thoughts most appreciated !

Kind Regards

I think Allan, that with this sort of malfunction, the car needs to be interogated. Any less an action is resorting to pure guess work which can be frustrating, wasteful of time and money and often less than satisfactory.

We know that there have been Sat Nav problems in the past and that as far as I can recall, there was a Sat Nav programme reflash made available to dealers and indipendents.

Would appreciate you posting how you achieved the repair whenever you have had it fixed. Always good to know the answer to such problems.

Kind regards.
