If I forget the phone in the truck, and forget the truck in the phone, and reconnect. It works great for the day. Truck sits overnight, and the next day is a no go. It will connect Android Auto via usb cable, but not bluetooth. Ive tried Everything in this thread so far, and nothing works for more than a day. I think I might have to go to the dealer and have them flash the pcm. thanks for all the suggestions guys.

Thanks, I will try that tonight!

Thanks. Yes, I removed the phone from the infotainment system, and I also removed the "my gmc" from my phone several times. maybe it will get better with time, or I'll have to get used to plugging it in all the time.

thanks, I'll look for that now.

Hi, New here. 2026 Denali HD. Just purchased 7/2/26. I am having the same issue. I just traded in my 2024 AT4, and the truck connected to bluetooth and Android Auto Immediately! Now, with the new HD, it connects when it wants to, which is usually not at all. I have to use the usb-c cable to get it to connect. Bluetooth won't even connect without the AA. Now after saying all that, I'll take a 20 min drive with the phone plugged in. Stop at a store, restaurant, etc.... Get back in my truck and DO NOT plug the phone in. The truck then decides at this point, lets connect BT & AA and work perfectly, ie how it should. I have deleted (forget phone) the phone multiple times. I guess I'll just get used to plugging it in every time. even though I don't think its good for the phone battery to have it on charge after it hits 100%. I have searched all over. No one else seemed to be having this issue, until I read this thread today. thanks for reading.
