I have done some testing on this using the same phone (15 Pro Max, iOS 17.2.1) in three different cars: Lucid, 2016 Ford Explorer, 2019 Jaguar I Pace. In the Lucid, if I switch to a different source, for example iHeartRadio, the widget continues to show the last played song from Apple Music with a pause icon over it. Also, sometimes, the wrong song is displayed on the widget. In the other two cars, both of which has a similar widgets, the correct source/song is always displayed.
Other bugs unique to Lucid:
- sometimes when the cameras come on (parking, etc.), the upper screen will not return to CarPlay even if it was there prior... it will go to the Lucid Home screen. In the others, it correctly goes back to CarPlay.
- occasionally, while using CarPlay the sound won't play at all. Other sounds in the car, such as the blinkers, work fine. This bug does not occur at all in the other cars.
Conclusion: it is Lucid's software that is creating these problems, not CarPlay.
