Carplay volume glitches with driving directions

[SenecaLotus2023]

Bumping this thread in the hopes that this issue might have been resolved. When listening to an Apple Podcast on the iPhone via wired CarPlay, if Waze interjects, the podcast volume remains almost muted. I also do not have this problem with any other car, and have noticed the same problem now across two different iPhones!

I have not had this issue - But to point out some differences, I connect via wireless to CarPlay. However, I have played music, listened to podcasts, and streamed the SiriusXM app all while using navigation. I will also add that I don't routinely use Waze, I more rely on Google maps. Wondering if it is something with the Waze app in combination the head unit?

Additinal information:
All updates through July 2025 applied to the Emira
iPhone updated to OS26

This happens to me when listening to a Podcast via Spotify. Interestingly, it does not have the issue when listening to music on Spotify. How does it know?
