Backup camera
Recently received this and works beautifully, it's far from the fastest but very much sufficient, the screen is not amazing but it doesn't need to be for its purpose, had to adjust the prongs for the AC vent but that took seconds, and after that fitted perfectly, LTE worked seamlessly, wifi is great, radio and sound are fine, and it works even after being in the sun for hours (so hot AF!) without issues.
My only question is about the backup camera, I double checked the cable continuity and that the camera actually works, but only works once every 10/20 times I put the reverse (it's connected to the rear backup lights), and I have to open the app for it, my camera has the "convenience" cable, but I'm not sure where to connect it to in the radio, I think it's the one labeled "19 BACK" in the pics above but I'm not sure, I'll appreciate some help.
