I bought a NAC with display and after connecting everything to the car the system didn't start, I thought I had made the wrong connections and I double-checked them several times but nothing to do, black display off, no sound.
what is the first problem of NAC with CANBUS 2004 system? that doesn't even turn on? help me.
