13.6 Tesla head unit

I just received mine and it looks great. I found a cable that let me use the factory GPS https://www.amazon.com/gp/aw/d/B00RZCF67S?ref=ppx_pt2_mob_b_prod_image and

I ditched the conversion for the USB and Aux input and instead purchased this USB and Aux passthrough to replace it.

My unit came with a connector that goes to the OBDII port and used this splitter to hide it and allow the port to be available for testing and my wifi LTE device. I unlatched the stock port and connected the splitter and one of the split ports snapped right in where the original was located.

I also found a cable that I think will retain the connection to the rear entertainment system and allow the DVD/Bluray to be displayed on the new head unit. https://www.sonicelectronix.com/item-107321-Axxess-AX-TOYRSAV.html


There is a cable I cant figure out where it goes, its a 16-pin cable one side is 16-pin male and the other is a 16-pin female, and the label says “Tie Line” in Chinese. Most if the wires are straight through except for 3 of them that go to a module thats shrink wrapped. Anyone know what this cable is for?

Edit: I figured out what the cable was for. It goes inline with the AC controls and I believe it is there to change the output of the head unit from 12v to 6v but not sure what its used for. It does connect into the input for the head unit passenger airbag light, so it could be that.

 

So it relocates the AC controls?

 

i got a light lidup on the dash since installing the radio , anyone else ever had this problem ?
