Through a friend, I was able to get the new 26.15 update installed. Keep in mind, my radio is a retrofit in a 4th gen 1500 so my experience may be different than everyone else's.
The update is being rolled out as an OTA slowly starting with a small set of build dates / VINs. Dealers won't be able to get you the update until your build date / VIN is added to the rollout.
Overall, I did not notice any major differences yet; things might be a smidge more responsive but overall no changes. The heated / vented seat controls are in their right spots but we'll see if they're still there tomorrow or the day after.
