Setup and Installation
The M22 HUD is designed for easy plug-and-play installation. It is compatible with all vehicle models.
- Connect Power: Use the provided USB cable to connect the M22 device to a USB port or cigarette lighter adapter in your vehicle.
- Placement: Place the M22 on your dashboard, ensuring it has a clear line of sight to the windshield for projection.
- Power On: Start your vehicle's engine to power on the device. The M22 will automatically turn on.
- Satellite Acquisition: Upon startup, the small icon on the product will flash continuously, indicating that the device is collecting satellite signals. Speed data will only be displayed once satellites are successfully located.
- Reflective Film (Optional): For improved visibility during bright daylight or to reduce reflection, you may apply the included reflective film to your windshield where the display is projected.
Important Notes for Satellite Acquisition:
- In garages, under overpasses, or within dense building areas, satellite search speed may be affected.
- If another GPS device is installed in your car, it may interfere with the M22's satellite search. Avoid placing two GPS devices together.
- Vehicles with metal film on the windshield may also affect satellite signal reception.
