Navigation head unit has a black screen now. after the battery went dead.

To reset the 2015 Isuzu MU-X audio and navigation head unit, you can try the following steps:

Turn off the vehicle and disconnect the battery for at least 30 minutes.

Reconnect the battery and turn on the vehicle.

Press and hold the power button on the audio and navigation head unit for at least 10 seconds until the system restarts.

Try using the buttons and see if they are working properly.

If the above steps do not work, it may be necessary to consult the vehicle's owner's manual or contact a Isuzu dealership for further assistance.

Dead battery? Short in the dash? Computer locked up? Sounds like a question for the dealer.

IF NONE OF THE ABOVE SOLUTIONS DOESNT HELP THEN CHECK THE CD UNIT IN THE BACK THEY TEND TO GO BAD GIVING THE SAME BLACK SCREEN RESULT.

it was a common prob with those cd changers in the boot/trunk disconnect it and let the head unit connect to it if still no good and the wiring/connectors are good the cd unit is faulty

This happened to my 06 325i, the navigation and instrument cluster displays are not controlled by the same computer, mine had to go back to the dealer for a reprogramming, hope this helps. let me know.

2002 RL Acura Navigation screen is black

Alot of cars loose the navigation when the battery goes dead. I see your cars battery could be at the end of its life.

If this is the case you will need the dealer to reprogram the unit.

THERE IS USUALLY A FUSE BEHIND THE UNIT IT SELF AND CHECK YOUR FUSE BOX

IT MIGHT BE UNDER THE STEERING WHEEL CLOSER TO THE DRIVER DOOR OR UNDER THE HOOD CLOSE TO THE BATTERY OR ACROSS ON THE PASSENGER SIDE

you can try disconnecting the battery for 30 minutes. it sounds like the m-ask/ ccc(head unit) has failed. It generates the picture for the i-drive screen and is the main module in the audio system (most bus).

Hello There.

Thats an interesting one. My first suggestion would be to look at the DVD navigation unit in the trunk, does it have any sign of life, i.e will it eject the map dvd is there a blinking redlight etc, if there is nothing then thats most likely your problem if there life in it then I would suggest having a closer look at all the connections in the trunk. You need to remove the side cover in the trunk and check the connections.
If the above doesn't help, my guess would be your head unit has the fault.
The cheapest way to get this repaired is by process of elimination. If you think the DVD unit in the trunk is faulty I would buy one from ebay if you find this doesn't solve your problem you can always resell it on ebay without losing money and the same with your head unit.
Hope this helps. Good Luck.

If my answer has helped you, please rate me on Fixya.

Many Thanks.
