Has it ever worked? If not, back to the dealership and let them sort it. If so, it may be your radio got fried. The radio in my 2021 lost Wi-Fi and Bluetooth a few months ago, yet radio and Sirius still worked fine. Radio was replaced at dealership. Thank goodness for extended warranty!

You could sell these! I'd buy one Well done

Well, dealer says there is a short in the radio. Extended warranty should cover it.

Niklasbraun - I think so. I pulled the negative cable yesterday and let it sit for a while. Some of my settings got lost, so I'm pretty sure it was long enough for a reset. Still same issue. Gray Add Phone button... Can't add via Android Auto either. I took it to the dealership today. I'll see what they come back with. $144 diagnostic fee!!!! That will be applied towards the repair.

PhilB, I will do that. Redwngr - yes. And tried both an Android and an Apple phone. With the connect phone button grayed out, it doesn't seem to matter at all.

You were right -- computer on wheels. I started to do as you suggested, but with the 'extra' panel on top of the battery, I got a little scared and decided not to. It's not as simple as just undoing the positive lead. I have to unbolt the panel on top, pop it loose, and make sure none of the extra wires and fuses get messed up. Then I might be able to pull the positive lead.

2021 1500 AT4 truck with a Bluetooth issue. 4 days ago my Bluetooth seems to have died. In the morning, phone was connected, everything is fine. Come back to truck later that day, my phone won't connect. Do a forget phone, and try to reconnect and the Connect Phone button is grayed out, so I can't connect phone. Also tried through Android Auto, and the connect to My GMC screen just sits there. The phone never sees the Bluetooth from the truck. Wife's Apple phone is the same. I called onstar who ran their script and after ten minutes said you have to take it to the dealership. Anyone else have this issue? What fixed it. Ami just SOL?

The center dash screen on my wife's 2023 Acadia Denali has just started going black every time a mobile csll comes in. Once the call is over, screen comes back to life. Anyone else experiencing that issue?

Thanks Bwoodsmn. That's what I was afraid of.

I've got a 21 AT4 with the IOS-GMC infotainment system. There is a way to get a split view of radio and your call history.. (I hit home button twice and it shows) Does anyone know if that can be changed? Rather than seeing calls, I want to see the map. I use Android Auto and Google maps, but noticed that it's the same for Apple Car as well

So, I have a 2021 AT4. I've not been through the manual and fuse blocks like y'all. Y'all have more energy than I... However, the only thing I have found that retains power is the old 'cigarette lighter' connection. Everything else shuts down. One of the USB A ports retains power 'for a while'. I think it's about ten minutes (the same as the radio if you don't get out of the vehicle) Don't know if the newer model years have that connection or not, but for me that still works That port is also the only thing strong enough to power an AC/DC converter to run a laptop computer.

I have a 2021 AT4 with the 6.2L. I'm getting better gas mileage now than with my 2014 with a 5.3. I've been pleasantly surprised at the fuel economy. Especially on long highway trips.

I could have sworn I added the RC storage to my list in Amazon, but I can't find it. So, I searched for it on Amazon, and I am now wondering if I am boing crazy because I cannot even find the RC version of underseat storage on Amazon. @Jettech1 I don't think you've posted an Amazon link to the storage unit -- could you please? If you have, then I am just blind as well as crazy....

Would love to see pictures after install

Agree with smit303! I use them on dimly lit roads and twisty mountain roads quite often. Helps to light up the edges far better than low beams.
