The radio fuse (for the car) is fine.
There is no fuse for the head unit. The diagram shows that you can add one yourself but I live on the edge so even when I wire an amp to the battery I don't use an inline fuse.
I found out the previous installer had cut off the Pink Wire (Braking Wire) and the Orange Wire (Reverse/Back Up Wire) as flush as you can get to the wiring harness plug...
To solve this I had to cut into the wiring harness plug about 1/2 inch so I could splice the extremely short wire to a new longer wire. In fact it's not even techinally spliced, it's being held in by the pressure of the wires squeezed together. Stays on just fine though it's surprisingly sturdy. It was still attached perfectly fine when I took the head unit out after I tried to get it work properly.
The thing is you NEED the Braking Wire to be grounded in order for the unit to turn on at all. This explains why the unit had a power button red light was illuminated but pressing the power button did nothing.
So I worked my magic and rewired everything from scratch. I plug the head unit in and it turns on, awesome, I press the Open button and the screen starts to come out, but it stops. The screen is displaying
but the touch screen only works when I switch to AUX, it comes up with the option at the top of the screen to switch to RADIO and that's the only part of the touch screen that responds.
Unfortunately this is as far as I could get it... The Up button which normally tilts the screen up would not work, in fact many of the buttons would only work intermittently.
I accidentally push the Up button into the unit, flimsy pos oh well, so that's why I've taken it apart in the photo.
I'm not really sure what else to do. This is a chinese fuckered head unit... I want to use an amp at some point and it doesn't even have RCA outputs (not that matters, I can use speaker wires straight into the high level inputs but still)
If it matters at all... I spliced into the extremely short Reverse Wire but I didn't ground it or do anything with it I just put E tape on the end of it. I figured it's not really necessary to wire it to anything because it's just there to activate the back up camera (if one is installed). Maybe I'm wrong and it needs to be grounded idk. Also the photo of the wiring harness plug is old. I found my E tape and isolated all wires with tape. No wires are coming into contact with wires that shouldn't therefore causing any issues.
