GM says that they'll do an OTA update of the Bolt's telematics, based on your VIN. I checked and the advisement was "press your OnStar button" They don't mention whether or not there's a charge for folks like me who don't have an OnStar subscription, but my Bolt is a 2020, bought new in November of 2020 and has about 23,000 miles on it.

Is there a charge?

As an aside, I find it more than a bit stupid on GM's part to not have had 4G capability from the start; the phase-out of 3G was planned many years ago.

What say you?
GM cars are 4G.

Well, I guess I can confirm that at least on my 2020 some of the functions are 3G. Today the time did not update for daylight savings time like it did every time before. It was set to update automatically from the cell system. I had to switch it to manual. I do not have an active OnStar account, and I have not had that system updated by the dealer.

Hmmm... If the clock updating automatically says that it's operating on 4G, then I'm good to go. A friend and I were going to lunch, and he happened to be watching the clock and SAW it update. I've noticed in years past that it always took a while, sometimes a couple of starts.

Okay, I give up. I now longer know what to think. I just went out, manually changed the time back, them switched it to automatic update from cell network. It immediately corrected the time. I am now not sure what GM is talking about. I don鈥檛 know if there is any 3G functions in my car or not. As far as I can tell, everything still works, including the MyChevy ap.
