I am having a similar issue. CarPlay refuses to work. I’ve done everything correctly, - I followed every step suggested in this forum, making sure all settings on phone were correct, 3 different cords, had my husband and mother try their phones and those didn’t work either. I recently purchased a new phone and that phone and new cord also doesn’t bring it up. . I have noticed as well that when I go to Media it doesn’t show anything as plugged into the USB connections even when there - so it’s nit just car play. All of the USBs work for charging so I am thinking it is maybe a truck software issue?? It did work the first week then there were a few days where sometimes it would and sometimes it wouldn’t. Now it has stopped all together. I have the Uconnect 4c w/o Nav - truck is a 2019 ram 1500 bighorn.
