Refresh infotainment - Audio cutting out for 1-2 seconds at a time and other issues

[DubVBenz]

I have a 24 1500 SLT with the refreshed infotainment, and have been having some issues:

 

• Audio will frequently cut out for 1-2 seconds several times within the first few minutes of running. This has happened on to sources from USB and Android Auto.
• After increasing my USB drive to about 15K songs, the truck indexed and used the flash drive as a source for a couple of weeks before basically just giving up. It acts as though no usb drive is plugged in now. I've purchased a USB M2 SSD to see if a speedier filesystem will improve this but have not tested yet
• Offline maps disappear  - I am not paying a subscription to use my freaking navigation system, so I downloaded offline maps, and have done so several times. After a couple of weeks they disappear and my navigation shows nothing

interestingly enough, I did the Infotainment reset  by holding down the end call button to try and resolve these issues. After doing so, my speed limit indicator that is 100% populated by the cameras and not a database stopped working and my cluster shows nothing. I know people assume this data comes from a GPS database, but my observations tell me it's from the cameras based off of:

• My rural, dead end street has a speed limit of 30MPH, but the sign is almost near the front of the road. My cluster used to show the limit as 55 (I'm guessing the default), until after I reached and passed the sign
• I have noticed that if a sign is obstructed or too far from the road, the speed limit would not adjust when passing it.

 

For the audio cutting out issues, I've seen lots of people complaining about it on the refresh models, so I assume it's well known. I'm hoping there will be either a firmware fix or hardware revision before my warranty is up. Having such a glitchy system on a brand new and expensive vehicle is not ideal.

I'm one of those that is positive the speed limits come from a database and not from camera.

 

Many many many times I have driven in locations where the limit shown on the dash was wrong -- even though we had driven past signs that cameras would have been able to read. 

 

There are several places in my 'usual' travel areas that speed limits have change and new signs installed.  The truck still displays the old speed limits.  

 

I also drive some places often enough that I know where the speed limit changes.

Sometimes traffic is heavy enough that me and the camera don't get a chance to see the speed limti sign -- speed limit displayed by truck changes anyway. 

 

No way speed limit is camera based. 

 

I'm sure they must update the database (in the newer vehicles that use googlemaps ) from time to time.

Just do me a favor... don't respond to any post or comment I create. For some reason, you seem to be compelled to be contrarian on every comment. I don't care about your inaccurate assumptions about the speed limit readout. I posted this seeking suggestions for the audio cutting out. So.. yes, please, just ignore anything I post, since you seem to think whatever I post here and elsewhere is always wrong anyways.

@redwngr is correct. This gmc/Google system does not read signs. F150 does. It is using the Google database for speed limits. 

You are the one that made a comment about the speed limit signs.

1 - There may be a radio update to fix the audio cut, and there likely is one available.  Give the dealer bulletin # 24-NA-100 and tell them you have audio drops, they will update to software Y172.

 

2 - USBs are finicky on the new and the pre-refresh radio.  

 

3 - Offline maps.  They don't work how you think/want it to.  You MUST have the subscription active to use the Google built-in navigation.  Offline maps work ONLY when cell signal is lost, so if you have the subscription and it loses signal while driving, the "offline" maps will step in to support the signal loss and allow the navigation to keep routing you.  It is NOT an actual "offline" mode.  If you choose not to subscribe, use maps through Apple CarPlay/Android Auto instead.

 

From the owners manual:  

 

Internet Connectivity

Google Maps relies on a subscription data plan for full functionality, including availability of offline maps. With an applicable connected services plan, Google Maps can be used offline when driving through connectivity dead zones by auto-downloading offline maps prior to going offline.

 

4 - Speed signs.  Its based on the navigation data.  

 

From the owners manual:

Speed Sign Display

Shows sign information, which comes from a roadway database in the onboard navigation system, if equipped. The sign will show “− −” when offline maps are unavailable.

I'm not sure why you even to bother post.

You ask questions and then trash the responses of those trying to provide information regarding. 

(not just my responses)

We're trying to help, but you are unwilling to accept help.

 

Clearly, GM's don't work the same as your beloved Benz vehicles.

Maybe you're should just switch back to them....

I just had my radio replaced because it was locking up and the audio was cutting out.  My build is Y175, is this the most up to date version?  The audio still cuts out every 20 minutes or so, would Y172 fix this or probably not?  Thank you!

Y175 is the latest and greatest.  Last time I did a radio, no way to revert back that I saw.

My 2024 google offline maps work with no subscription.  I can type in a address and it loads and works fine. And I have used it with my cell not in truck.  You just skip when it says you need a subscription for this. No don't. It works off maps built in to nav system.

Gotchya, thank you!  Have you had any luck with getting the audio cut-out glitch fixed or is it something that’s just going to always be there?

Honestly?  Not sure.  I have a 2022.5 that is Y175, I don't have any glitches.  I'm just an LT though so no Bose and amplifier.

 

I do know there's an audio issue with trucks with the amplifier that can occur with Y171, Y172 and Y175.  They want the amplifier replaced.  Here's the PI on it from GM - MC-11011689-0001.pdf

You’re the man new dude!  Helped me out so much throughout the years.  Hopefully I can repay the favor one day.  I’m going to show this to the dealer.  You have a friend if you ever find yourself in Illinois my dude!  Thank you!

Just messing around some more.  If I disconnect my Bluetooth and create a WiFi network and connect the radio to my phone as a WiFi hotspot instead of Bluetooth the radio doesn’t cut out.  As soon as I turn the Bluetooth on the audio cut outs return.  
 

I’m thinking this is more of a Bluetooth connection issue than anything else.  So my question is what connects when I connect my phone via blue tooth?  Is the Bluetooth built into the radio or a separate module?  Thank you in advance!

Bluetooth hardware is internal to the radio receiver module (aka the radio).  Radio also has WiFi antennas.

OP , my audio would cut out 3 or 4 times quickly with in the first 2-3 minutes that the vehicle was first started for the day. Then worked fine. No other issues with screen features. I was going and trying to figure out out is it CarPlay or my Bluetooth or iPhone. While I was trying starting up with CarPlay connected or not , repairing my IPhone over a short period of time and not being able to correct problem . I then received a warranty update letter from GM for a Software Wi-Fi Module Update on my vehicle I had dealer do the update and haven’t had an audio cut out sense ! It took about a 45 minutes at dealer ! Hope this info helps. 
 

Updated was done about 2 1/2  months ago ago .
