Thank you, I had the same thought. A website/list to check against would be great. I would think tech hardware on the current-gen AT4X (all nearly identically optioned) is the same. But things get quietly upgraded all the time.Hard to say. Software updates apply to specific hardware. If you have different hardware than a 24 or 25 truck, then you may not need updates that they need. You may have to see the dealership to find out if you are missing updates. I don't know of any websites that would list the relevant updates. It would be nice if there was one.
It is currently at the dealer for a known ACC fault, which I believe is software-related. I will ask them to check everything out!
