Alright, so me and my friend was trying to install a backup cam we got on eBay with the correct harness. After wiring up correctly, we tested the camera by shifting into reverse, but nothing happened. So then we checked to see if the wiring is correct, and it is.

Not knowing what could be the problem, my friend took out his headunit (Subaru's stock touchscreen HU) from his FRS and tested it in my car to see if it's the headunit or wiring we're having problems with. When using my friend's headunit and shifting it into reverse, it WORKS!

I have a 2015 stock Scion's touchscreen HU. My friend has the Subaru's stock touchscreen HU.

So now we know that the wiring isn't an issue afterall, it's the headunit... Does anyone know what could be wrong?! Where would the correct wiring go to in my Scion's stock touchscreen HU?...

P.S We also tried going in the diagnostic menu, but couldn't get it to work so it has to be the wiring positioning differs from the Subaru's HU...

P.S.S We also read every DIY thread on how to install the backup cam, but everyone is doing it on a Subaru's HU, not a Scion's HU...
