DiPlay on DiLink 4: USB, Upgrade Loops and Display Issues

Available evidence

#11 explicitly confirms Han wired projection and touch on 0.2.0 / iPhone 13 Pro Max / reported iOS 27.0. It also reports media-key failure, repeated USB prompts and slow initialization. Android and year are unknown.

#42 reports Qin / DiLink 4 / Android 10 / iOS 18.7.1 connection failure after 0.2.0→0.2.6. #26 is a separate Han upgrade loop report, not the same setup.

#92 reports unchanged display scaling on Seal EV / 2022 / DiLink 4 / Android 10 / iPhone 13 Pro / iOS 17.7.2 with 0.2.8. It is a scaling issue, not a failed CarPlay installation.

What to try next

Use the compatibility checker with your own system values. Keep unknown fields unknown. For wireless, try the current built-in hotspot setup first when available; compare USB to isolate transport problems.

Changes and checks in 0.2.12

Existing Wi-Fi / Same LAN connects the car and iPhone to the same external network. Join it in system settings, save its credentials, keep Bluetooth on and disable client isolation. DiPlay does not join Wi-Fi or change the default route (PR #223).

Virtual 16:9 maps support compatible launchers without a physical cluster. Experimental DiLink 3/4 routes add scoped cluster handling and retryable stock-state restoration; DiLink 5/5.1 keeps priority. No DiLink 3 windshield HUD or verified DiLink 4 HUD profile is claimed (PR #171/#182/#187/#213).

Same LAN supports open, WPA2-Personal and WPA2/WPA3 mixed networks; WPA3-only, enterprise and captive portals are outside its current scope. Allow multicast discovery. A contributor tested a standalone build on a 2022 Han DM-i / DiLink 4.0 / Android 10 / firmware 21.1.21.2401160.1; that is not a vehicle test of the complete signed 0.2.12 release.

Retest repaired DiLink 3/4 cluster routes, scan recovery, wheel modes and firmware-specific hotspot startup. General stutter, calls/Siri/microphone, iOS 15 startup and colour/theme reports still need fresh current-device evidence.

Changes and checks in 0.2.13

DiLink 4 native cluster casting and picture controls improve; contributor confirmation covers a 2022 Seal/DiLink 4/Android 10. DiLink 3 projection has checked recovery. Turn cards retain their two-minute expiry, map scale adds 125%, and battery/wheel-service recovery is scoped. Independent DiLink 3 call keys/dashboard cards are off by default; stock idle restoration is not a prior-state snapshot (PR #243/#260/#265/#285/#296/#297/#304/#306).

Fixed dock choices can change live; Automatic transitions reconnect. Optional square-canvas rotation and split-window areas preserve video/touch mapping but increase decoder load. The experimental side panel is off by default and closes on rotation/split-screen changes (PR #245/#246/#277/#284).

Retest Android 9 P2P, model-specific cluster restoration, hotspot repair and call/audio paths on the target firmware. Buffered music still needs physical pause/seek/navigation/call/Siri checks; contributor setups do not validate the complete signed release.
