+- [ ] **Xcode**: Enable CarPlay capability in Signing & Capabilities
+- [ ] **Google Play Console**: Declare Android Auto integration → set "Navigation" category
+- [ ] **Google Play Console**: Upload Android Auto screenshots (required for listing)
+- [ ] **Signing**: Both platforms must use production signing/distribution certificates
+
+### Testing
+- [ ] **Android Auto**: Test with DHU (Desktop Head Unit) emulator
+- [ ] **Android Auto**: Test on real car head unit with USB
+- [ ] **Apple CarPlay**: Test with CarPlay Simulator in Xcode
+- [ ] **Apple CarPlay**: Test on real car with Lightning/USB-C cable
+- [ ] **Voice guidance**: Verify TTS integration works while CarPlay/Android Auto is active
+- [ ] **Rerouting**: Verify auto-recalculation reflects on car screen
+- [ ] **Trip end**: Verify navigation session ends cleanly on both platforms
+
+### Compliance
+- [ ] **Android Auto Quality Guidelines**: https://developer.android.com/training/cars
+- [ ] **Apple CarPlay HIG**: https://developer.apple.com/carplay/
+- [ ] **Privacy**: Ensure location data usage is clearly documented in privacy policy
