Car Play Woes... STILL (iOS 26.3 beta)

[Batt4Christ]

I connect my iPhone 17Pro to my truck via cable (and have changed cables in troubleshooting to no avail).

Playing music via the Music app works fine
Receiving phone calls works fine
But calling up Siri to send a voice-to-text message results in simply the color shift/aura to the truck's screen - but no sound. If I select a received message to be read - no sound. GPS voice prompts do not play through.

When pressing the button on my steering wheel to call up Siri for any request, the truck's screen shows the color aura around it... But no sound whatsoever.

Have you tried fully deleting the phone connection on the phone and radio side? Any OTA updates for the radio?

Another thing to check is the volume associated with iPhone sound. Pick and play a moderately long message through your CarPlay interface. While it is supposed to be audible, slowly turn up the volume. Same goes for nav voice prompt. You may need to do it a few times.

Getting the right (or even audible) balance between sound sources can be tricky. Different head units handle it differently. However, most can be adjusted while a specific sound source is playing.

Hope this helps.

Could also be a problem with your truck's system and software. Have you checked if any updates are available for your truck's system?

id suggest, as others have posted already to delete the connection and re connect from scratch. Car Play has been rock solid (both wireless and wired) since the very early betas of 26.0 for me...so either your vehicle is not up to date, audio is muted or it simply needs to be reset. Also might be good to post your truck model and year to see if anyone else with same model/yr has the same issue.
