What was actually tested
PR #8 reports next, previous, pause and resume over wired CarPlay on DiLink 5.0 / Android 12 / eng.build.20251111 with iPhone 15 Pro / reported iOS 27.0.
On eng.build.20260118, the same contributor reports car-hotspot long-press Siri and working car microphone. The wireless media-key fix was not separately retested; other key-routing firmware is untested.
If the buttons do nothing
- Check the app version and keep CarPlay visible when testing long-press Siri. Short press is not the supported Siri gesture.
- Start music from the iPhone’s CarPlay app and check whether another car source (radio/native music) holds the buttons.
- Record whether next/previous and play/pause fail together, and whether it happens after switching audio sources.
- Export logs and provide firmware and connection method. Source-level media-session changes do not prove your unit emits the same keys.
Do not assume custom bindings
Open PR #91 proposes customizable key bindings and floating PiP. It is not part of the reviewed release. #46 contains a newer-version success reply but no setup details; it cannot certify every BYD.
