- For vehicles with Auto AC, please mount the factory AC board on the back of our unit like shown in the video. For vehicles with manual AC car, just connect the factory AC connectors to the back of the unit.
- To make connections to the head unit, just match connectors and/or labels. If on-screen AC control is not working, check if 8 pin connector with green and green/black or white and white/black wires is connected to the back of the unit.

- If you have OEM touch screen unit, you may need main harness with big connector, different radio antenna and USB adaptor like the picture below. Please contact us if you received harness not matching your OEM connectors:
- Here is the picture of two different kinds of main harnesses. Depending on the batch, you may or may not need to use the main harness adaptor:
- The connector for OEM backup camera may be mismatched if you have no big connector for OEM radio. You need to make sure the male RCA labeled 'CAMERA' goes to the brown OEM connector indicated in below picture.
- How to retain the Rear entertainment system: the OEM rear screens are powered. You just need to feed RCA video signal to the male RCA in our harness labeled "2nd/3rd row video". We will provide the USB to RCA converter box if we know that you have RES before shipping. The female RCA from the box connects to the male RCA in our harness labeled '2nd row video' and '3rd row video'.
- The sim card can be put into the back of the unit or the sim card reader cable we provide. T-mobile would be better to work in our unit for now.
