Be careful doing this as well.Check out this thread, someone has figured out how to replace the air card. Great info if this happens out of warranty.

The aircard is incredibly easy to swap out, but I believe it needs to have the same software version flashed on it as your radio. One of the reasons why updates and reversions fail on the UConnect when the aircard is dead is because it updates the aircard, too. The update process doesn't have any kind of contingency for a bad aircard which is why you get stuck in a bootloop.
I originally swapped my dead aircard with another one from a 2020 Challenger. The aircard was exactly the same part number and hardware revision. It did work, initially, but would lose altimeter data after a few minutes. However, the card was fine. It never lost connection to 4G towers, so it wasn't going bad. I tried flashing an update to my radio and it failed exactly as it would have with a dead aircard.
The UConnect software varies between FCA's brands based on vehicle performance features, despite it looking and operating the same, but I don't believe aircards are as plug and play as we think. It's still possible I managed to get another bad aircard, but this radio was practically brand new and the altimeter data always worked for the first few minutes, but would stop afterwards like clockwork.
I made a post about doing surgery on my radio, but this was prior to noticing the altimeter issue: https://www.jlwranglerforums.com/fo...th-dead-navigation-using-a-uas-as-parts.59137
