Thanks for starting this quick-reference instruction thread!

In terms of WHEN to use these instructions, a few situations where this type of reboot has helped are below. Hoping we can add to and build this list further, as we learn of more situations where reboots help:

- screen randomly goes black - with or without audio still going - and turns back on​

- navigation randomly is outputting metric units while everything else is in standard units​

- Android Auto and/or CarPlay issues (YMMV on this one...)​

- audio system and/or phone issues​

Also of note is that the infotainment system never really shuts down, as called out by @andrew28. Perhaps this means we should ALL do the reboot on some regular frequency as a matter of regular maintenance/health, rather than waiting for issues to trigger it...?

And last but not least, props to @andrew28 for finding and bringing this tip to the forum. I think it's in the running for "tip with the most application."

 

Yes, thanks @andrew28 for first finding the video! I plan on doing this monthly (or when I remember) to, hopefully, avoid future issues. It would be nice if Honda had a reboot option in the settings section.

 

I'm currently at 1539 hours uptime since I last did it back in April or early May. I tried doing it today but failed multiple times in getting the reverse/neutral button to register in time. It would be nice if an option for reboot is available when holding the power button for the display audio(I think this is how the previous generation display audio did it).

 

I have mine set to lock the doors when I shift out of park. I just start the car and repeatedly press reverse until I hear the doors lock, then I move immediately to neutral. Even with that, it took two tries today to get it right. Left hand on the start button and right hand doing the shifting. I think the reason there is no reboot option on the settings menu it that it would be illegal to disable the back-up camera if there was any chance the car may be able to move - hence it is tied to the gear shifter which is in neutral with your foot on the brake during the procedure.

 

Is this different than Settings / System / Factory Reset? That appears to "reboot" the system as well, and is what I use when my Apple Carplay freezes ("unable to start").

 

It is different in that it will retain all your settings. Factory reset wipes everything pertaining to icons, wallpaper, presets, etc.

 

I came across a simpler way to reboot the head unit:

• While the car is ON, press and hold the audio system power/volume knob for 3 seconds.
• When the pop-up menu asks if reboot is desired, select "YES."

This tip comes from the steps you'd follow to reactivate the system after a 12-volt battery replacement (attached).

The steps seem to work for any 2016+ Honda, and a quick youtube search showed this reboot working for the Clarity, CR-V, and Accord. (On models without a power/volume knob - like the 2019 Clarity - the "AUDIO" button is pressed/held instead for 3 seconds.)

A helpful summary of "quick reboot" steps for Honda and other manufacturers is in the article below. Honda's reboot steps and effort are definitely the shortest and simplest among the other listed manufacturers: https://www.consumerreports.org/automotive-technology/how-to-reboot-your-cars-infotainment-system/

I remember trying it with the car ON(as in ready to drive) and it didn't work. Not sure if this works in ON mode(as in pressing the power button again after accessory mode). Going to check it out when I get a chance.

 

Does anyone know how to manually reboot the infotainment? I read online that it was done by pushing in the volume knob for 3 seconds, but that doesn't seem to do anything for me. I haven't had any crashes with Android Auto (1 month of ownership), but I have had slowness and wanted to do a reboot.

 

It's not an easy process (it may take a few tries).

When you go to turn the car on, make sure you are prepared. (Foot on brake, hands free, cords out of the way etc...)

Hit the power button (with your foot on the brake)

As fast as you can shift into reverse (it has to engage), then immediately shift to neutral. I watch the shifter lights to make sure that it engaged gears.

If successful, when the "legal disclaimer" comes up, the OK button should be completely grayed out.
You can confirm in Settings > About > Runtime

 

THANK YOU! This saved me a trip to the dealer. It took about five tries but I finally got it to work.

 

Have you experienced any issues with the infotainment screen going blank and/or restarting itself? Or just being proactive in rebooting?

 

I mentioned this on Verier's channel, I wonder if something goes wrong and the latest software update doesn't fix anything - will the reverse reset hack not work anymore. It is mentioned in the release notes :/

I wouldn't be surprise if they fixed it. They already fixed the below in the Accord on a previous build.

• Display Audio reboots when operating the shifter quickly between Reverse and Drive.

Our current method is Reverse and Neutral.

 

I can't get it to reboot after latest update... I've tried maybe 5 times but I feel like it's not great for the car so I don't want to try that many times

 

Ya, agree... the soft reboot steps are quirky and aren't the most natural process. The separate steps for full factory data reset are directly thru infotainment system (Settings --> System --> Factory Data Reset).

I haven't had reboot issues in 1.5 years of ownership; I've only experienced a "dark screen" which could've been related to night/day settings. My car does the soft-reboot on its own when it loses antenna signal.

 

OMG thank you so much for this! I searched for like two hours last night for a solution to my problem and could not find one. Took the car to the dealer today and they didn't know what was wrong either. Just got the car brand new 4 days ago so I was a little saddened to see my android phone wasn't working properly with it on bluetooth or android auto. Dealership called me after I had left and told me to look into resetting the infotainment center which led me to this post. And it worked!

 

You might have to get use to issues like this. I have been battling my radio for years now due to Bluetooth drop outs and disconnection issues.

 

There is a way to reboot the center display without doing a factory reset. Here it is described on the 10th generation Accord forum in post # 17.

Finally figured out how to reboot the head unit!

Completely by accident today, I figured out how to reboot the head unit on my 6MT 2.0. As far as I know this only works on the 6MT, as you can't perform this operation with the 10AT. Why would you want to do this? The reason is that the head unit itself doesn't turn off with the car, it just...

www.driveaccord.net

I checked it on my car - it works.

Here is a copy of the text with instructions:
"#17 • Feb 7, 2019 (Edited by Moderator)
This seems like an easy way to reboot, especially for 6MT users, but being a developer I feel like this is likely to get patched.

After reading through the factory diagnostic documentation for the head unit I found over on XDA, I found a fairly easy way to reboot without any trickery. This is designed to work like this from the factory, so is unlikely to change.

Power vehicle to ON, this is one step past Accessory. No brake pedal, hit Start button twice.

Hold HOME/SOURCE/POWER buttons until beep to gain access to diagnostic menu.

Hold HOME button until you gain access to the "Toggle In Line Diag" menu. This is a simple on/off toggle menu meant for QA at the factory. The current selected setting will be "Completion". Select "Incomplete". This will open the Line Diag Tool view.

Note here: you may feel you are stuck in this screen as the back button will not work and there is no Return button like other Diag menus. At any time in this view, you can hold HOME/SOURCE/POWER and gain access back to the main Diagnosis menu. Holding HOME here will allow you to toggle back to "Completion".

This view does a bunch of automated system tests, there are two that are manual tests. All of the boxes should change to Green color after a few seconds as the automated tests complete. You will notice 2 Gray boxes on the right, though. These are manual tests for the microphone and volume controls on the steering wheel. Hit the Volume Up or Volume Down button once, then hit the Microphone button (looks like a face) once. These boxes should turn Green and allow you to tap the Exit Diag button.

Another note: the factory documentation says you will need to clearly say 'Testing' after hitting the Microphone button on the steering wheel for that test to complete. I found this not to be the case on my 10AT Sport. The box turned Green immediately after hitting the button.

After this it will cause a system reboot of the head unit. The first time takes a bit to get used to. After that it is very easy to toggle into this view and reboot the system.

One more small note for my last post, just trying to cover all bases for people not familiar with these things.

If any automated tests fail, you will not be able to get out of the Line Diag Tool screen without doing what I said in note above. Also, if the test fails, it will not trigger the In Line Diag menu to go into Completion, which means the automated testing screen will open every time you turn the car on.

As I said above, holding HOME/SOURCE/POWER and then holding HOME will allow you to toggle the In Line Diag back to Completion which will cancel this screen from opening on every car start."
