The VJOYCAR DIY wireless alarm is designed for easy installation. It usually involves attaching the magnetic siren to a steel surface under the hood, connecting the red and black cables to the positive and negative terminals of the car battery, and placing the air pressure sensor into the cigarette lighter socket.
Reset procedures vary by model, but many VJOYCAR trackers can be reset by sending specific SMS commands (such as 'RESET' or 'BEGIN123456') to the device's SIM number. Consult your specific model's user guide for the exact command.
If your VJOYCAR HUD is not displaying correctly, ensure your vehicle is compatible (typically gasoline cars manufactured after 2008). Ensure the OBDII cable is securely connected. You may also need to access the menu to calibrate the speed unit (KM/H vs MPH) or select the correct protocol.
VJOYCAR offers specific accessories for different Tesla models (Model 3, Model Y, etc.). Always check the product description to ensure compatibility with your specific year and model, such as the 'Highland' or standard versions.
Firmware updates are typically handled via a USB connection to a Windows PC using the 'Uplink' software available from the Vjoychina website, or via OTA (Over-The-Air) updates for connected smart devices.
