Where is the fuse for the navigation system? - Acura 2004 MDX Touring with Navigation S

Question edited for clarity.
Question moved to Yes, Model category.

It is one of the most complex electrical systems on a modern vehicle. You will only get the full wiring in a service manual or from a subscription with AllData. You can however usually bring up part wiring diagrams. The search query is

..

XL7 not XL-7 (the dash matters big time)
i'll guess its a dash.7
REDUX
in your post you said fuses are good (tested too)
have you checked and reseated the connectors on the OBJECTS that fail>?? (that is free to do)

we now learn many things fail on car,
even HEAD LIGHTS?????
and no statement of what works. in total!
does car drive perfect night and day?????
just a clue here, and win big. huh>?

I can't drive your car and see all those many things failing,& that are. ok .. and what does not fail....

but this car has CAN-bus (or the like)
a NETWORK for sure, and bus structured.

and does not work like some 1990 Vitara.
at all, not even close to same. (forget them...)
it's a BUS system.
each switch you throw sends a command on the bus.
it's failing I bet because of communication errors
that you fail to see because you did not use a real scan tool at the time of failure.
it must be scanned while failing !

cant fix it if its not broke,...(unless you drive
scan and log data. like i do all the time for all intermittent of any kind....)



does it fail engine running?
is running battery voltage at 13.3 to 15vdc
if voltage is low all computers in car will go nuts. (same with your cell phone)
this is a fact and what i check first?
valid battery voltages first.
2nd after fuses, (done already)
then scan it. using a real scan tool
not some relic.
a real tool can see all CAN buss errors
U codes top the list.

P1,p2, p3 and B codes too.... all seen.
failing.

you can buy tools
rent tools
or get the car scanned failing at any ASE shop.
car parts store may have junky or relic tools.
(i can name 10 that are)
some tools only do old federal P0xxx codes. say some old 1996 tool.

try a real shop and win. really

Hi Eric. I would recommend repeatedly pressing the navigation eject button about 5 times to see if the unit will respond. If not, there is a fuse in the right rear area above the battery. On the trim cover that folds down to access the battery is a fuse label. Pull the fuse for the Navigation system and leave out for 10 minutes to let the unit cool. Reinstall the fuse and try once again to eject the disc.

If the fuse is blown it could certainly have something to do with it.

there is a fuse that power on the navigation system under the passenger dash board replace it and your navigation system should turn on

There are several fuses for your Navigator's radio and stereo system. Which one are you looking for? If you are haveng problems with your radio, it is most likely not the fuse anyway.

Before you get too involved in chasing fuses, please read this article: Where's The Fuse?

The navagation module shares a fuse with the Rear Control Unit, The DVD Player (If equipped) The Rear Integrated Control Panel (without DVD) It is fuse #4 (15 Amp) in the Central Junction Box (CJB)at the right kick panel. The Navigation Module also shares fuse #22 (10 Amp) with the Auto Dimming Interior Mirror and the Audio/Navigation Control Unit.

The Audio/Navigation Control Unit is also protected by fuse #31 (20 Amp) and fuse #7 (5 Amp) also in the CJB.

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

Had same problem with 2008 Honda Civic.
Note: you will need anti-theft code so get it first!
Solution:
1. Turn ignition off.
2. Look for fuse box under steering wheel.
3. Remove fuse #35 which is for the Navi-audio unit.
4. Then re-insert the fuse. This will reset the system.
5. Turn ignition on and the Navi-audio on. Buttons WILL be working now.
6. The unit will request for the anti-theft code for Navi-audio system. Enter the 4 digit code....Yippee!
However, I lost all my radio preset stations. Thankfully my saved destinations in navigation system were intact.

Had the same problem with my '03 330xi. Navigation worked fine but radio and CD did not work at all. I opened the fuse box located in the glove compartment to check the three fuses associated with the navigation system and radio. #7, #39, and #41. All three fuses were intact so I put them back in. I then put the key into the ignition, turned it to position 2 and miraculously the radio came to life. I guess it acted as some type of reset?
