I’m on R13 as well with no desire to lose things such as the outside temperature and the Bluetooth key. I have a few glitches, similar to most, such as the Autohold fault which sporadically appears on boot up.
The one thing I do have that I don’t think I’ve seen before is when using CarPlay for a phone call, the first time I ask it to call someone, there is no sound. The call connects, but there is no sound at all.
If I ask it to call, cancel it then ask it to call again, the sound works perfectly. This didn’t happen in my old car, so it’s not an issue with my phone. Frustrating, but I’ll put up with it for now.
