🔌 How to Connect

  1. Plug the RC26 into your car's wired CarPlay or Android Auto USB port. Use the cable that came in the box — aftermarket cables may cause connection drops.
  2. Turn on your car's ignition. The adapter will power up and display a welcome screen on your car's infotainment display.
  3. On your phone, go to Settings → Bluetooth and pair with the adapter. Once paired, the connection will happen automatically on future drives.
  4. Accept any permission prompts on your phone (contacts, notifications, etc.) to enable the full feature set.
💡 Tip: After the first pairing, your phone will reconnect automatically each time you start the car — no need to repeat the steps above.

✅ Compatibility

What You Need Requirement
Your Vehicle Any car with factory wired CarPlay or wired Android Auto
iPhone iPhone 6 or newer · iOS 10.0+
Android Phone Android 11.0 or newer
Not sure if your car supports wired CarPlay? Plug your phone into the car's USB port with a Lightning or USB-C cable. If CarPlay (or Android Auto) launches on the screen, the RC26 will work.

🛠 Troubleshooting


Connection Issues

CarPlay / Android Auto won't connect, or drops out mid-drive
  • Multiple phones: The adapter can only maintain a stable connection with one phone at a time. If a second phone tries to pair, it may kick the first one off. Disconnect unused devices.
  • Outdated OS: Make sure your phone is running the latest version of iOS or Android. Older system versions sometimes break the handshake.
  • USB port: Try a different USB port in your car if available. Some ports are charge-only and don't carry data.
The adapter restarts or reboots while driving

This almost always points to the physical USB connection. Check that:

  • The cable is fully seated at both ends (adapter side and car side)
  • The car's USB port isn't loose or worn
  • You're using the original cable — third-party cables can have intermittent contact
Some apps on my phone don't show up in the car screen

Not every app on your phone is approved for use while driving. CarPlay and Android Auto each maintain their own list of allowed apps. The adapter mirrors whatever the platform permits — it can't bypass those restrictions.

Performance Issues

The interface feels sluggish or laggy
  • Too many apps open: Close background apps on the adapter (not your phone). Running navigation, music streaming, and a messaging app all at once can strain the processor.
  • Overheating: Make sure the adapter has airflow around it. Don't bury it in a closed glovebox or under a pile of cables. Heat buildup will cause the system to throttle performance.
  • Cache buildup: Periodically clear the adapter's cache through its settings menu to keep things snappy.
Video playback stutters or buffers
  • Check whether the WiFi signal is weak — the adapter relies on a stable connection for streaming.
  • Run a speed test to confirm your network can handle the resolution you're playing. If not, drop to a lower resolution (e.g., 720p instead of 1080p).
  • If you're using a mobile hotspot, move the phone closer to the adapter.

Other Common Questions

The clock resets every time I start the car

The RC26 doesn't have an internal battery, so it can't hold the time when it loses power. Don't worry — it syncs automatically as soon as it connects to the internet. Just give it a few seconds after startup.

Can I install extra apps on the adapter?

Yes. As long as the adapter is connected to the internet, you can download and install additional applications through its built-in app store or via APK (Android-based system).

📋 Tips for Daily Use

  • Give it a moment. After starting the car, the adapter needs about 15–30 seconds to boot and reconnect. Don't unplug and replug it impatiently — that just resets the process.
  • Keep it ventilated. Place the adapter somewhere with airflow. Tucking it inside a closed center console may cause it to overheat on long drives.
  • One phone at a time. If multiple people in the car have paired before, turn off Bluetooth on the phones you're not using to prevent connection conflicts.
  • Restart occasionally. Like any smart device, a restart every few weeks clears temporary glitches. Simply unplug it, wait 10 seconds, and plug it back in.
  • Keep firmware updated. Check the settings menu periodically for over-the-air updates that improve stability and add features.
