Reset navigation system after replacing battery

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.

Presumably you disconnected the battery when you did the fuel pump and PCM? It also looks like the PCM has to be programmed with the VIN Number.

I think you will need to access the Nav System with a professional
scanner or scan tool & then use manufacture trouble charts, to even know what the system is supposed to do, & how to diagnose it

Hopefully a repair shop, if they want the job,otherwise blow out
your wallet at a dealer

Check with the dealer for a MAP CD update.

Any car with a Factory Anti-Theft System does this whenever battery power is lost. If your owners manual doesn't address this, you will have to contact a GM Dealer to get the system reset. Sorry!

Wow. I have a Mark VIII, so I can empathize...they really load these things up with electrical controls, and I know from experience to start with basics-get a digital meter and check your battery voltage when the car has been sitting for a few hours, it should be 12.5 volts. Next, check voltage when running-it should be about 15 when first started, gradually dropping down to about 14.2 after a few minutes. I cannot emphasis how important good power is on these power-hungry systems.
Check your connections at the battery, make sure the terminals are immaculate and the lugs are too-and you might try removing BOTH clamps and hold them together for a few minutes to discharge electrical components. Hook them back up (always hook up the positive cable first), and start the vehicle and let it idle for 5 minutes-then gently drive it for another five, to reset sensors. Assuming your battery and laternator are good to begin with, if you still have the problems you describe, you probably have a major malfunction with modules or even the ECM, something the dealer will have to diagnose with a Tech 2 scanner.

Turn your key to on position and turn on a/c switch, next remove positive battery cable wait 30 sec. and turn key off and replace battery cable. This will reset you ecm, "computer" If not need the codes reed in it, good luck.

Hello and welcome to FixYa!

If the battery light is on, I strongly suggest that you have the battery charged. It can be an indication of a weak battery or a faulty alternator. If the battery light still on after charging then the problem will surely be on the alternator itself. If that's the case the alternator should be replaced to resolve the problem.

If the battery won't hold charge even on a new alternator then the problem will be on the battery itself. It surely is in the end of it's service life and replacement will be necessary.

You may try to reset it to by removing the positive battery connector, letting it sit for at least 5mins. then reconnect it again. This will reset the system and can get the battery light off.

Hope this helps and thank you for using FixYa! Have a good one!

Found the SN and CODE on the white label attached to the side of the glovebox. SN begins with a "B" followed by 8 numbers. The 4 digit code can be entered into the navigation system to unlock & reset the unit after a power disconnect.
