Apple Carplay stopped working Accord 2018

Looking for assistance:


I have a 2018 honda accord. I have been driving it for a mere 2 weeks. Apple carplay was working wonderfully for 2 weeks until yesterday. No changes to the phone, just stopped working. Now I cannot get it working. I have tried the following:


Change Cable

Change USB port

Update OS (now 11.1.1)

Reset Network settings

Disabled all restrictions

iCloud backup performed


Phone model is 7 Plus. The car recognizes the phone, works in USB mode as well as bluetooth mode. In the smartphone settings on the car itself, it has the phone as enabled. I click connect and it just says cannot connect, no smartphone device detected.


I'm really at a loss here. This should be plug and play but it is most definitely not.

iPhone 7 Plus, iOS 11.1

I just had this issue with my new 2018 Accord. You Hard Reset your car my removing the positive on the battery terminal. Mine used a #10 to loosen the nut. Super easy and not worth he wait at the dealer. Not to be rude but I’ll place the steps below.

- open hood

- unclip housing for red positive on battery to access nut (if yours has one)

- loosen nut (#10 socket worked fine for me)

- remove positive connection from battery

- wait a few moments (30 seconds should be fine)

- replace positive back on battery terminal

- tighten nut

- clip red plastic housing around positive terminal (if yours has one)

- close hood

- start car

- plug in phone

- test CarPlay


I hope this helps and is super easy, don’t let all the steps away you. It’s literally as easy as removing the positive terminal and the putting it back on.

I was originally going to do the hard reset as suggested by ddugas1970 but I found a ”Factory Data Reset” in the Infotainment Center under Settings, System. I took a chance and it worked. Took about 5 minutes to complete and afterwards I had to reset some of my personal settings like radio stations, door lock preference, etc. Like ddugas1970 don’t know how long it will last. I believe that the bug sits with Honda and that sooner or later a fix will be applied. I will let you know if I uncover anything else that can help.

I have taken the vehicle into a honda dealer and they were unable to get carplay working with any other device or cable. At this point there is no solution but Honda says they will look into the matter further and try to find a solution. It could be hardware but that is strange because the USB port is working fine for accessing music. I really think this is a software issue, but its just a gut feeling. So, as it stands my fully functional Iphone 7 plus will not work with carplay in my 2018 Honda accord, nor other apple devices that we tested with.


Once fixed, I will post what the issue and resolution was.

How did you perform your factory data reset.? Mine is greyed out and won't let me select it. I parked my car in the garage to connect to my wifi and every time I attempt to perform a software update, it states I can't perform this action while in motion. The car was turned off and on multiple times. At one point I saw the ability to download over wifi but it stated again that the action couldn't be performed while in motion. I don't think this has anything to do with iOS 11.2.5 (which I did install yesterday and this is the first time it has ever happened). I guess I will disconnect the negative connection on my battery.


Don't you just love new tech....

Last week I attended a Honda 101 class that the dealership in Manchester CT offers. You get a free oil change for attending. The service manager claimed to know nothing about this issue and disregarded the tech bulletin that was posted from Honda on this website which I showed him.. He was pompous and arrogant and did not want to hear about any other issues that customers brought up, as well. All we got was the typical blaming the customer replies. He did acknowledge that my Display unit should not be freezing as it did twice but did not say bring it in and we will change it. Apparently that was a big issue om some earlier models.

I am having the same problem with Apple car play. I just updated iOS to the latest that dropped today. I hope it fixes it. But in the meantime. I have reset the factory settings... now my satellite radio does not show the channel Id’s and logos for all the channels like it did before. Has anyone else experienced this? Do you know how to get the logos to reappear?

FWIW, I have used my Apple CarPlay very nearly daily for four months now (and most days, at least twice a day) and never had the issue of CarPlay not starting up until yesterday.


I've also "crashed" the unit a few times month by using the iPhone (instead of the CarPlay console) so I'm sure there are bugs but overall, I'm very happy with the performance.


As far changing the background on the unit for 2018 Honda Accord Sport, Google came up with several possibilities (Google for: change background 2018 Honda Accord Sport)

Hi, I just got my car this last Friday and my carplay isnt working on my 2018 Honda Accord. Honda dealership said its an update issue. Your post is from January and the dealership said they are working on this issue with carplay. They make it seem its getting fixed soon. Has your carplay kept working after the hard reset? Any suggestions for me? Also have you gotten any update or changes to your car from apple or honda? Thanks for your time
