Yeah, if you want to go from one to the other you pretty much got to delete both from each other and start fresh with the connection you want. My issue with wireless is it makes it a freakin nightmare trying to hit wifi with my phone. If I try connecting to my starlink mini or my dash cam, it keeps autoswitching back to carplay on its own. Going wired solved that.
As for the audio drops, I've not noticed that myself, but I've had carplay refuse to connect a few times. Solution I found was to just reboot Uconnect. hold power and enter (center of two knobs) at the same time for like 20 seconds until the screen goes black. Once it restarts carplay works fine again. Could try that the next time it drops audio and see if that helps.
Also make sure both are updated to their latest versions. I know everyone is paranoid about updates on these trucks with the whole 98mph ecu flash issue, but the Uconnect update itself should be OK. Also, you could try the beta version of iOS 26 and see if that works better for you.
