Well the vehicle dynamics and speed sensor is at 0 because of your VSS wire not being connected or connected to the wrong wire.
For the no voice guidance....
There should be a speaker icon on the bottom right of the map screen. Does it have an X through it. See page 31 of the manual. If there is an X that's to turn off the voice guidance. If it's a speaker, then that's very weird.
If you don't see it... hit MENU and then MAP, then touch [Displayed Info].
The Displayed Info screen appears. You want to make sure Show Mute Button is VIEW, and then make sure there is no red X on that icon.
For the VSS wire:
Check the
MENU - SETTINGS - HARDWARE - 3D Calibration (or something with the 3D in it, should be just to the right of CONNECTION STATUS).
That should (at best) say simple hybrid, but any other errors in there should show up. I don't know if there is something else in there. It could be.
But I ran for months without my VSS wire and I don't remember, but I thought I had voice guidance and distance left in your route. I don't know why that should be linked to the VSS wire.
You could make a stink and get the dealer to hook up the VSS wire correctly, that might make everything come back.
