A: Contact Mercy Lion's customer services, after we checked it is indeed true that after the customer provided the correct car model, model year, and pictures of the car rearview mirror housing from different angles, the dashcam housing we sent to the customer is still not suitable for installation. Our handling method is as follows: 1. Reconfirm again and re-send the correct dashcam casing to the customer. 2. Since the casings of individual models vary from different countries if after re-confirm we do not have a suitable casing, we will give the customer a full refund. Our after-sales service is guaranteed, free of concern to shop on Mercylion shop.

① Plug-and-play, please check if the plug is correctly located.
② Please check if all three wires are properly connected when the fuse box is powered on. For the 3-prong connector of the power cord output, measure whether the two red and yellow wires have power.

Make sure the black ground wire is in good contact and is not insulated when the car is painted. If it still cannot boot normally, please contact online customer service immediately.

We have two types of fuse box hardwiring kits. One is equipped with an ACC converter, which only has constant power connector and grounding connector; Another type is without a converter, with three connectors: constant power, ACC, and ground wire. As the hardwiring cable is a backup power line in the package, we will send it randomly. Please refer to the actual received goods.

A: The WiFi can only be connected when car engine is started and dash cam is working. If can't, send the screenshots of WiFi & APP Page!
