Dashlinq CA FI Head Unit Reverse Camera Installation

[Gts86.au]

Hello community,

I have purchased a Dashlinq Ca Fi Toyota head unit for my gt86. These are Android OS head units that have alot of cool things going for them. This unit was bought to replace my OEM PQZ60-00537 Fujitsu head unit.

I got the unit and was hoping to be able to connect my Toyotas OEM camera to this device but I am struggling to get a signal to the device.

Please see the attached images I have included a PQZ60 wiring diagram and some of the cables that I believe are part of this solution but maybe I'm wrong

If you look at the wiring diagram. You can see the CN4950 port which I thought is the units video port its got the V+, V-, CA+ which I think is the trigger cable and Ground.

I created a video tester lead for the purpose of running a few experiments.

1) I have tried connecting the V+ to the BACK cable on the dashlinq system and the V- to the video in on the device but no go.

2) I have tried connecting to V+ and V- to the video in and the BACK cable to the CA+ cable but no go.

3) Im thinking now that the CN4800 port is maybe the the trigger wire as this port references V+, V-, and CA+ and PKB (is this parking brake) , but I am unsure.

Can anyone suggest anything?

Thanks
