Intermittent Radio On Start Up

[MishawakaKirk]

Thanks JT...
I missed the specific area the where the version is, until your post. I'm at the same version as you: Y172.
Based on reading backwards, it seems as if the 'Fix' may cause more problems (steering wheel controls, fan control, etc.) so for now, leaving it alone. The few intermittent radio issues, while irritating, are minor.

So just waiting on GMC to figure out what to do with the L87 recall....as I frequently take 1,000 mile trips

Yep - the radio issues are much less of a big deal compared to the potential for our engines to fail on us, right?

I received an OTA update last night. First one of these OTA updates that I recall getting - the other software updates have been at the dealer. Although the update initially failed to install for me, it eventually installed successfully. Too early to tell if there is anything good to come from this update (e.g., whether it finally fixes the audio dropouts). I went from software version Y172.6.1 to Y177.6.1. See a few screenshots below.

Does anybody have access to GM Techline and can get me the USB download of that Y177 for my Tahoe? I have a 2021 with a 2023 IOK radio installed so I have to do this manually every time there is an update. I am currently on Y175 and hoping this fixes a few audio issues I am having.

Nevermind, I got it from Techline myself and updated it with USB. Now at 177.6.1

Anyone notice any differences in the update from past?

After the update my radio still cuts out several times after starting, and now my maps take forever to load. in my case it went from bad to worse.

Oldish thread bump, but I've had my 2022 Yukon XL for about 14 months and it's always had the radio cutting out issue. Just looked at my current version and it's Y167.4.2, so clearly far behind. Is this something the dealership will generally update at no cost (I actually believe I have CPO coverage until June this year)? I tried checking for over the air updates and it's telling me there are none, which clearly isn't the case. I do see there is a TSB 25-NA-121 that appears to be the most recent version that should, I assume, update me to Android 12. Anyone have luck with that update?

Here is latest bulletin: https://static.nhtsa.gov/odi/tsbs/2026/MC-11027878-0001.pdf

I have an appointment Friday at my Chevrolet dealer because I have a variety of software defect issues, including the radio, screen and various electronic control settings.
