Connect the power harness as follows:

• Red (Constant Power): Connect to a full-time 12V hot source (battery or fused constant power circuit).
• Orange (Ignition Sense): Connect to a switched ignition circuit so the device powers on/off with the vehicle.
• Green: Not used (cap and isolate).
• Black (Ground): Connect to a solid chassis ground or battery negative terminal.

Important: Always use an inline fuse on the constant power lead.

Be default when the key is turned off:

• The screen will stay on for approximately 5 minutes.
• The device will then enter sleep mode for up to 24 hours.

This behavior:

• Preserves the last known GPS location
• Speeds up boot time when the vehicle is restarted
• Reduces power draw while keeping the radio ready

Connect antennas to the rear ports as labeled on the MX1:

• LTE Main: Connect the long, narrow LTE antenna (primary cellular antenna).

• LTE DIV (Diversity): Connect the stubby LTE antenna (secondary LTE antenna).

• Wi-Fi: Connect the stubby Wi-Fi antenna.

• GNSS (GPS): Connect the GPS/GNSS antenna.

For best GPS performance, mount the GNSS antenna:

• On the dashboard
• Near the windshield
• With a clear view of the sky

Avoid mounting:

• Under metal
• Under heavy trim panels
• Inside glove boxes or trunks

• Plug the handheld microphone into the connector on the bottom-left of the device.
• Use the included clip to mount the mic within easy reach of the driver.

• Attach the mounting bracket to a secure surface (dash, console, or under-dash).
• Secure the MX1 into the bracket using the included screws.
• Ensure airflow around the unit and avoid direct heater vents.

• Route cables away from sharp edges and moving parts
• Use zip ties to secure all wiring
• Do not coil excess antenna cable tightly
• Avoid placing antennas near large metal surfaces when possible

• All power wires securely connected and fused
• LTE antennas connected and upright
• GPS antenna mounted with sky view
• Microphone connected and mounted
• Device secured to prevent vibration damage

Verify:

• Confirm LTE signal and network connection
• Confirm GPS lock and location reporting
• Test PTT / voice audio with the microphone
• Ignition behavior verified (turns on/off with key)
