For anyone that comes on this in the future you cannot permanently attach that wire to ground the radio is smarter than that. If you tie it with ground and turn your key on and off as many times as you want the buttons will still stay greyed out
It works till you turn the car off then back on. Then essentially to make it work again u have to unhook from ground and reattach. Just hook to the pos on the parking brake switch switch
Hi, i made ground as you made, but after turn off and turn on the engine again, the system is blocked again, i think that i need to add a button to open and close the circuit, what do you suggest?
