The carriers are getting rid of 3g bands. so if you have stuff like collision detection, it will stop working
3G Network Retirement
3G Network Retirement
Is this something built into the Entune system, or the truck’s computer? Or is it something paired with your phone via Bluetooth? I’m aware of the phasing out of 3G, but this is the first I’ve heard of it effecting our 4Runners. I have an ‘18 SR5.
if your car as cellular remote start, or you use entune to do something over the cell network like download apps etc.. then when the 3G is discontinued those features will be lost.. thankfully we don't use any of these features on our 2014 so we're not going to miss anything.
We went through this with our GX460 though, that has cellular remote start but apparently since ours is a 2019 its got the upgraded hardware for 4G, 2018 and older has 3G connectivity, so thats sad for those folks.
