FAQ
Frequently asked questions
Compatibility, legality, and the practical stuff.
What is Pillion?
An Android app that mirrors your phone's screen to a Yamaha motorcycle's built-in TFT dash over Bluetooth, so you can use any navigation app on the dash instead of being limited to Garmin StreetCross.
Which bikes are supported?
Any Yamaha that uses the Garmin 'Communication Control Unit' (CCU) and works with the Garmin StreetCross app. Community-confirmed so far: MT-07 (2025), R9 (2026), MT-09 (2024 & 2025), MT-09 SP (2026) and XSR900 (2025). Very likely to work on other models on the same platform too (XSR900 GP, Tracer 9 GT+, Niken GT, TMAX, XMAX). More reports are welcome — post your model in the Discord.
Do I need a special key or pairing secret for my bike?
No. The NaviLite auth is universal — there's no per-bike key to extract. If your phone is already bonded to the dash over Bluetooth, you're ready.
Does it need an internet connection?
No. Pillion connects directly to the dash over Bluetooth Classic. No internet, account or cloud is required while you ride. (Your map app may want data, but Pillion itself does not.)
Is there an iPhone version?
Yes — iOS support has landed. It's the same app as Android (one shared Compose codebase), with iPhone capture handled by a ReplayKit broadcast extension. You install it by sideloading with a free Apple ID (via AltStore, SideStore, Sideloadly or TrollStore) — there's no App Store build, since Pillion is a non-commercial hobby project. A downloadable IPA is coming in the next release.
Can I ride with the phone screen locked?
On Android, yes — Pillion can keep streaming to the dash while your phone is locked, which saves battery and heat. It needs a quick one-time setup (a single ADB/Shizuku step, no root), and exact behaviour depends on your device and Android version (built against Android 16). See the Discord for device-specific tips.
How smooth is it?
About 14–15 fps at 480×240 over Bluetooth on an MT-07 (2025) — smooth enough to follow a moving map. Frame rate and quality are tunable to save battery.
Is this affiliated with Yamaha or Garmin?
No. Pillion is an independent interoperability project, not affiliated with, authorized by, or endorsed by Yamaha or Garmin. It contains no Garmin or Yamaha code — only an original implementation of an observed protocol.
Is it legal to display a phone screen on my dash?
Local laws differ on what may be displayed or operated while riding, and it may be restricted where you ride. Check your local rules — it's your responsibility. Read the safety guide before using Pillion.
How do updates work?
Pillion checks GitHub Releases once on launch and shows an in-app 'Update available' banner with the changelog when a newer build exists. Tap Get to download the new APK.
What's the license?
PolyForm Noncommercial 1.0.0 — free to use, modify and share for non-commercial purposes. Commercial use requires a separate license. It's a hobby / interoperability project.
Ready to put your map on the dash?
Grab the latest APK, sideload it, and start casting. It's free for non-commercial use.
