Prius 2024 LE issues with google maps

Used to be you could disconnect the 12 volt battery for a few minutes to do a hard reset on all the systems so they're back to factory spec. That's likely the easiest way. I'm sure Toyota's software engineers have all kinds of bugs and a lack of funding for more staff to get them resolved quickly.

Alternatively, you can go through all the settings available and figure it out manually through trial and error...

 

Google maps losing voice = do not know, happens very rarely with mine so I haven't looked into it

Low audio = Just activate the voice command then exit voice command (you can press the button on the steering wheel, you can do ok google, you can do the mic button on the stereo, whatever method you want to get into a voice command). Low volume is the head unit turning down the stereo but not resuming normal volume when you're done, sometimes it's dumb and doesn't restore volume. Going in and out of a voice command mode makes it restore volume.

Honestly go try waze and see if you have the same issue you do with google voice. Worth a shot to narrow down the problem.

 

Anytime I had an issue with my wife's phone on AA I just forcestop the maps app and it reloads on-screen and resumes working.

My phone works perfect though since it's heavily debloated with ADB and shizuku

 

Sounds like a nightmare trying to get modern day apps to work on a super primitive and poorly coded Toyota infotainment screen. Toyota is woefully behind everyone else in onboard software systems that integrate with web apps...

 

Yea you can get better results with aftermarket screens and some moneyORknow-how.
Sad that each car company tries to reinvent the same wheel.

 

Chiming in on this as I've had this very issue and was about to post asking about this.
In my case, the common trigger to cause Android Auto to act up is my turn signal warning system. When Maps is speaking while music is playing and the warning system beeps it will periodically trigger this issue. As mentioned, telling google to tell me the weather will get the audio level for music back, but the voice assistant is mute the rest of that ride.
I've disabled the warning beeps in my cluster's settings. No issues the last 24 hours, but we will see. I'm hoping there's a better way to work around the issue as I appreciate the beeps to warn me of cars in the lane my turn signal is on for.

 

Easy workaround, just don't use signals...

 

To get the audio back to full volume, try just pressing the voice command button on the steering wheel or saying "Hey, Toyota".


For those that want to know what's happening, I believe it's the following:

There are two systems that are interacting - the telematics unit and the audio head unit. When the telematics unit needs to say something, it's supposed to send something like this to the audio head unit:

<command to reduce volume>
"message to the driver"
<command to restore volume>

Either the software in the telematics unit is not always sending the restore command, the audio head unit software is not responding to the restore command, or the restore command is getting lost/garbled between the two computers. The other possibility is that the telematics unit sends a constant signal to the head unit to reduce volume and then doesn't stop sending it when it's supposed to.

In any case, the workaround is to just force the telematics unit to say something to cycle through the commands again. The quickest and easiest is through the voice command. Even if you don't tell the car anything, it will still respond with something like "I didn't understand that". But that's enough for it to resend the restore volume command as part of the process, which should return the volume back to its full level. Very occasionally you might have to do it twice if it fails the first time. The nice thing about the "Hey, Toyota" version is that you don't have to look down to find any buttons.



Auto dark - Requires a light sensor that doesn't come on the base trim. If you wanted that feature, you should have gotten an XLE.

Resuming Spotify after call - It's been a known issue that Android hasn't addressed for something like five years, so I wouldn't hold your breath. Quickest workaround is to change to a different music app and then switch back to Spotify. That should auto restart your music.


I also have to note that, between Lane Tracing Assist and Adaptive Cruise Control, it's pretty safe to leave the car in control for a moment to find and press any buttons/screens. (Assuming you're in traffic on a major road and not driving through a neighborhood or something.)
