I have had a 2019 Ram since late 2021 and from the beginning I have been able to use CarPlay but have issues when CarPlay on long drives (usually more than 30 minutes). After awhile, CarPlay will start a cycle of disconnecting and reconnecting. I usually just unplug and wait 20-30 minutes before I reconnect and it will work for another 30/40 minutes before the cycle begins again. I’m pretty sure it is the Uconnect software as I have tried multiple iPhones and they all suffer the same fate. Uconnect was updated over the summer but continue to have the issue. Not sure if it is what it is or if I need to replace the unconnect unit.
