I have a new Samsung S25 and my Ram is a 2020 with Uconnect 4 8.4. I don't think it works without being wired.The newer phones and infotainment systems can use Bluetooth. It's what I use without plugging in, but I have the latest of both. Seems I read about someone using different methods to connect, but that is just an extremely faint recollection.
I travel a lot and in order to use navigation I have to have my phone plugged in which means it is charging all the time. Does anyone use usb wireless adapters instead of having your phone plugged in?
