Setup & Installation
The Hogtunes BTS-U is designed for easy plug-and-play installation in 1999-2013 touring bikes, but its universal fit allows it to be used in any vehicle with a 12-volt power source and a 1/8" AUX input.
Wiring Instructions:
- Power Connection: Connect the red wire (+12V) from the receiver to a constant 12-volt power source (e.g., directly to the battery positive terminal or a fused accessory wire).
- Ground Connection: Connect the black wire (GND) from the receiver to a chassis ground point on the vehicle.
- Remote Turn-On: The blue/white stripe wire is a remote turn-on output. Connect this to the remote input of your amplifier (if applicable). If not using an amplifier, this wire may not be needed or can be connected to an ignition-switched 12V source to turn the unit on/off with the vehicle.
- Audio Output: Connect the 3.5mm AUX output cable from the receiver to the 1/8" AUX input on your factory radio or amplifier.
Mounting:
The compact design of the BTS-U allows it to be hidden inside the fairing or other discreet locations. Ensure the mounting location is secure and away from excessive heat or moisture. The unit is controlled entirely by your playback device (e.g., smartphone), so direct access to the unit after installation is not required for operation.
Operating Instructions
Bluetooth Pairing:
- Ensure the Hogtunes BTS-U receiver is powered on.
- On your smartphone or Bluetooth-enabled device, navigate to the Bluetooth settings.
- Search for available devices. The Hogtunes BTS-U will appear as "BTS-U" or a similar identifier.
- Select "BTS-U" to pair. A confirmation tone may be heard once successfully connected.
- Once paired, your device will automatically connect to the BTS-U whenever it is powered on and within range (up to 40 feet).
Controlling Music Playback:
All music playback, volume control, track selection, and other audio functions are controlled directly from your paired smartphone or Bluetooth device. The BTS-U acts as a receiver, transmitting the audio signal to your vehicle's audio system.
Maintenance
- Keep the unit free from excessive dirt and debris.
- Periodically check all wiring connections to ensure they remain secure.
- The unit is designed to be durable, but avoid exposing it to extreme physical shock or prolonged submersion in water.
Troubleshooting
| Problem | Possible Cause | Solution |
