I’m using carplay wired and also remote with iOS 15.5 no issues whatsoever since resets months ago. Also Garmin Nav is spot on
For me, it’s only ever wired CarPlay- always using the latest OS.
Standard 128Gb iPhone 13.
Yet I have boot delays, can’t connect issues and satellite position errors. The same as others are reporting.
Car is a 21MY EX.
Numerous resets, software update and new infotainment control unit have done nothing (actually made things worse) - I still have the same issues.
FYI I don’t believe you can have both wired and wireless CarPlay connections unless you disable Bluetooth/WiFi before plugging in - on mine, even with the cable plugged in it’s still using wireless CarPlay unless I do this.
An easy way to check is the delay in changing music track - it’s much longer on wireless CarPlay.
