Product Quick Instructions

1. Find the OBD port (computer diagnostic port) of the car

How to find it: Open Baidu/Google website - enter the year, brand and model of the car, where is the Plus+OBD port? Then Baidu/Google will prompt the location of the OBD port.

2. Insert the product into the OBD interface, turn on the power and turn on the work light.

common problem

1. Does the test product work?

Turn on the phone navigation, enter the target area, and drive to see if the phone is moving.

2. Why not block individual cars and trackers?

In the case of not shielding the original car navigation of high-end cars, the satellite receiving antenna may be on the roof of the car, and the interference wave cannot penetrate the metal carport, resulting in no interference. Using a mobile phone to locate the position of the base station will not be interfered by different factors, but the positioning error of the base station is hundreds of meters, more than a few kilometers.

But it does not affect the use of this product.
