There is a way, its just hella annoying access it.

1 Hold home+power+previous
2 Tap detailed information and settings
3 Hold back+power+previous
4 Tap system reboot

I find this can help with laggyness.

So I finally gave these steps a try… Two thumbs up!

First, because I was trying this without actually needing to do so (i.e., my wireless CarPlay was working just fine), ironically I was unable to get step #1 to work at first. I had to stop playback via wireless CarPlay and be on the home screen. I assume if I were having problems with CarPlay, this would just happen naturally.

But once I did that, with the engine running and the car parked (with the parking brake engaged, if that matters), holding Home + Power (pushing in the Audio/Vol knob) and “Previous” (the “rewind” button on the lower left under it) for a few seconds yielded a beep, and then this screen:



Selecting the last option, “Detailed Information & Setting”, got me this screen that didn’t mention anything useful:



But then, in a “hidden menu of the hidden menu” trick, holding down Back + Power + Previous (instead of Home + Power + Previous) for a few seconds got another “beep” and this screen:


Selecting “system reboot” rebooted the infotainment system without losing any other settings, and without having to shut off my engine.

I assume that had I lost my CarPlay connection that this would have resolved it.

Thank you so much for posting this! Every few months (probably 5 or 6 times) when I start my car Android Auto wireless flat out won't connect. The only way previously I had found to remedy the issue was to reset it and setup all my preferences again. Happened today and a reboot fixed it.

So does parking the car and then starting it again later after a long enough rest to have the car really shut down (versus some kind of sleep mode).

But the soft reset only takes a minute and you can get it working for the drive you're already doing.

When my wireless CarPlay connection gets dropped, and this was even before I found this soft reset hidden menu trick, I would just "live with it" for the drive I was doing and I noticed it would be back the next time (usually - sometimes it took two overnight or over dinner parkings).

Just parking to run into the supermarket wasn't long enough, but a 90 minute to 2 hour dinner at a restaurant was.
