This is a different model in the States. If this has a display for the Navigation there are controls to set for brightness and auto adjustment for day and night. These controls are reached within the programming of the Navigation screen and independent of the dash lights switch.
You are probably zoned out of making adjustments when the screen is dark. So you will need to tinker with this when you can see the screen better.
On our vehicles the headlight dimmer switch only controls the dash lights. Could be you had this vehicle serviced. Sometimes when an OIL CHANGE is done the service technician wants to reset the oil interval and goofs up some other settings in the process. Think about when the problem started and if someone else had their hands on your vehicle.

Does it go completely black or just dim? Most displays dim when you turn the lights on to make the display darker so its not too bright. GPS and other displays do this. Do you have any problems with any other of the car's electronics?

Pull the headlight switch and check for a burned connector, this will cause a poor connection and in turn dim headlights or no lights.

Below is your wiring diagram. So does the battery run down or not? At 12 volts, the battery should run down. Here are a couple things to check. The grey 20 gage fusible link from the battery to the alternator runs the stator coil. You could try jumping that with a regular 14 gage wire to see if the voltage will jump up (should be at least 14 volts). The other thing is with dual batteries (which I think you have), if one battery is bad, it could pull down your voltage. Try unhooking the negative terminal on one battery at a time to see if the voltage increases. Let me know if you have any questions.
