How can we
help you today?

A wireless adapter requires a factory-installed wired CarPlay or wired Android Auto connection. Connect your phone to the car with a data cable first. If wired CarPlay or Android Auto opens, an adapter is generally suitable. Check your vehicle with the compatibility tool or contact us before ordering if you are unsure.

Use the vehicle's USB data port rather than a charging-only port. Make sure Bluetooth and Wi-Fi are enabled, remove the old pairing record, restart the phone and device, then pair again. Android users should also confirm that the vehicle and product are set to Android Auto mode.

Check the audio output selected on the LAMTTO device and use the matching source on the car stereo: Bluetooth, FM or AUX. Raise the volume on the phone, device and car. For AUX buzzing or interference, Bluetooth audio usually provides the cleanest result; an AUX ground-loop isolator may also help.

Streaming apps require a model with built-in video apps or a compatible AI box, plus an internet connection from Wi-Fi or a phone hotspot. Standard CarPlay screens and wireless adapters do not run standalone video apps. For safety, use entertainment features only while parked.

Use a supported high-speed SD card, format it in the dash cam and enable Loop Recording. G-Sensor and Parking Monitor events create locked files that are not overwritten, so delete or format locked recordings when storage becomes full. Check your model guide for the supported card type and maximum capacity.

Parking monitoring normally requires a compatible hardwire kit and correct BAT+, ACC and ground connections. Confirm that Parking Monitor is enabled in the device settings. Because wiring and operating modes vary by model, follow the model-specific guide and use professional installation when working with the fuse box.

Only install firmware supplied for your exact product model and hardware version. Never use a file from another LAMTTO model. Open your model's support page or contact technical support with your order number, model name and a photo of the Configuration or Firmware Version screen.

Include your order number, exact product model, a clear description of the issue, and photos or a short video if available. Tell us which troubleshooting steps you have already tried. Complete information helps the support team provide the correct solution faster.
