Sat Nav Problem

My wife's 2012 Westminster has a "fault" for which no one has been able to identify the cause. It has the digital dash and the Navigation software, I understand, is on a flash or hard drive rather than DVD.

The problem is that it no longer gives voice guidance. You can set the destination normally, then the Navigation voice says something like "guidance will commence when you join the highlighted route" the arrow symbol proceeds along the route throughout the journey (but lane instructions and junctions don't pop up), and there is no further voice guidance until bizarrely at the end the voice guidance states "you have now reached your destination"!

Various people have set and reset the languages, adjusted volume, and changed on road/off road navigation. Re-installed the software etc etc.

A clue that may be relevant, when going through the Dartford tunnel my older 2006 Range Rover continues to proceed along the route even though GPS signal is lost. My wife's doesn't it stops and then jumps forward on exit from the tunnel. This may just be due to the different systems but I was wondering if there is a speed input that could be missing and cause this behaviour?

My logic being that it doesn't start the guidance because it doesn't know that the vehicle has started moving.

Any experience, such as how your sat nav behaves in a tunnel, or suggestions as to how to trouble shoot would be very welcome.

All the best for 2021

Thank you for your reply. If you mean power off and re-boot then yes as it had a new battery fitted very recently, and prior to that our local independent tried a software update and a "reset" which I assume is the same thing?

A bit more pondering today and I have almost convinced myself that it has to be the vehicle speed input that is missing and hence it doesn't know that the journey has started. Can anyone confirm where the signal originates (rear wheel sensor?) and how it gets to the Sat Nav - wire or MOST? Pointers to any diagrams, components involved or pin number/connectors much appreciated. At about the time this was first noticed the car had a blocked sunroof drain and water came above the headlining and down the very rear pillar (trim piece with the speaker) on the nearside. It knocked out the Parking Aid Module but there are a few other bits in that area including some MOST boxes which could have been affected. 2012 L322 Westminster V8 - Current
