Why is CarPlay no longer working in my 2019 RAM vehicle?

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

Well then, I learned something new from you and that is that USB-C ports are making its way into automobiles now. Great!

Russell, let me know how it goes as well.

A USB-C to Lightning Cable? Do you have a USB-C port in your DODGE RAM to connect to for CarPlay? Normally cars only have the standard USB port. Please double check. I believe that the standard USB to Lightning cable would have sufficed if you are talking about connecting your iPhone to the port of your RAM.

If you have ordered the USB-C to Lightning cable for something completely different then that is fine (For ex. charging your iPhone purposes outside of your car etc).

Thanks for the posting the picture.

Good Luck at the Dealer. I hope they can figure it out and I am afraid that what may happen is that the dealer will tell you that the head unit will need to be updated to keep with the changes in iOS version 14.

If you can reboot / reset the head unit and then try again with what you have then see if that works. You may have already done that.

Major issues with CarPlay are all over the place since the latest update(s) (14, 14.1, 14.2), including here, Reddit, anywhere you look. This is a huge issue. Here we have a brand new Acura TLX 2021. Our two iPhones XS Max used to work perfectly fine… till we upgraded to 14.2. Now CarPlay is not working at all and we've tried all the tricks and fixes suggested by the gurus.

Nothing to be done. It is quite a stretch that each car manufacturer has to fix things in order to correct something wrong with Apple iOS. Don't get me wrong, I'm an Apple power user and a fan. But let's call the shots correctly here. It's Apple's fault, even if in some cases a fix seems to work. Had I known, I would never have updated beyond 13.x, never. Lesson learned the hard way here. My phone is a tool, not a toy, and I expect it to work seamlessly after an update. At the very least, they should have warned us. My guess is that they simply didn't know.
