Apple CarPlay occasional connection issue

[sportse]

Here's what's covered by the software update:

The two main symptoms are;

Mistranslation of German Language

Black Screen

Is also includes the following;

A WIFI setting improvement

A Change to the “TEL-MUTE” status when using connect diagnostic mode

An improvement in handling certain audio files being played from a connected device.

A minor Android security update

First go to have the update installed today failed - it has to be downloaded from Honda before it can be uploaded to the car.

The download was still going after 1.5 hours and said it had maybe 1/2 an hour still to run at least.

Perhaps lots of dealers all downloading the update at the same time from Honda?

Hopefully it will be installed tomorrow.

Now updated.

So maybe my 0063 had a change that your 0024 didn't ?

Mine is a 21 model, so maybe was loaded with earlier software.

The new update has only been out a week, it may be that they only apply it if people are experiencing issues.

Nope, not fixed it

I've driven 4 trips today, on one of them I still had the black screen for maybe 10 seconds before the Honda logo came up.

When it's working properly the Honda logo comes up on the infotainment screen straight away after start, then fades and you have the telematics screen before the menu comes up.

Seems to only affect some cars, others never have any issue.

Mine also varies.

This morning it was almost instant but I've had times where it's taken 10 secs or more as you say.

Doesn't bother me as it's never failed to boot.

I had the impression yours completely failed to boot and you had to power down then up again.

[sportse]

There were/are two separate issues unfortunately

1) the delay in the infotainment screen starting up - could be 10 to 30 seconds with just a black screen. The update was supposed to fix that, but hasn’t.

2) separately, happens much less often, is where the system won’t recognise the phone - no matter what you do.

Power off and on and it still doesn’t work.

It can happen while you are driving and the connection just goes. Or it might be working on one trip, but when you go to continue and restart the car there is just a message saying no connection possible.

Some random time later it decides to work.

Has happened with two different phones, two different cables and also on wireless CarPlay.

[Kremmen]

Ah, right, never had that.

By the time I'm belted up, RDMS off and standalone Garmin set, for whole journey traffic, the headunit is up and ready with Google Maps.

Wonder if continuity of power supply is an issue?

[sportse]

One of the things that Honda recommended was disconnecting the battery for an hour, so they will have tightened it up afterwards but it’s still doing it.

It’s a strange fault, the dealer said no other customers of theirs has had it.

The sometimes long delay on start up seems to be more of a common issue. What car magazine had it on their long term jazz.

Hi sportse
tell me please do you using on both iphones screen time ?
Had same issues with phone not found and disconnects, i switched screen time off, 2 days no issues with CarPlay (iOS 15.4.1)

When you picked the car up after the software load did it boot quickly before you paired your phone ? Assuming the new software trashed all existing settings.

In the back of my mind is your phone maybe has some software on it that the headunit doesn't fully like and is having to check and load.

The phone hasn't been connected yet all the times when the boot issue occurred

Most of the time the unit boots up quickly, but every few starts it just gives you a blank screen for 10-30 seconds.
