Beeping when Canbus In and Out are wired together
Trying to install this in my Toyota. The Canbus In and Out wires were plugged in to each other right out of the box. SO I left it alone. WHen I got the deck installed, it beeps and goes to the phone app. Any button pressed it goes right back to the phone app. Also, I can't map any of the steering wheel buttons nor does my back up camera work anymore. I've triple checked all my connections and everything looks good. What am I missing?

My model is JY-TO160N4GS-1.
Maybe you need to go to the control app and program the buttons?
Mine had them wired together as well which I think is wrong but I left them that way. I don't have that problem though.
