Hy I maked.
My pioneer 3.3v tip,rin pin.
My 5v PWM 490hz Low RC 32kohm and 100nf 49HZ.

Not work, just band button.
My code:

int r=0;

const int VOL_UP=1;
const int VOL_DN=2;
const int NEXT_TR=3;
const int PREV_TR=4;
const int MUTE=5;
const int CALL_UP=6;
const int CALL_D=7;
const int MODE=8;

int elozo_gomb=0;

void setup() {
  pinMode(12,INPUT); //ring
  pinMode(A1,INPUT); //wheelADC
  Serial.begin(9600);
}
void loop() {
 
    int gomb_megnyomva = gomb_bekeres();
    if(elozo_gomb != gomb_megnyomva)
    {
      delay(20);
      gomb_megnyomva = gomb_bekeres();
      if(elozo_gomb != gomb_megnyomva)
      {
        elozo_gomb=gomb_megnyomva;
        if(gomb_megnyomva == 6 || gomb_megnyomva == 7)digitalWrite(12, HIGH);

        switch(gomb_megnyomva) {
         case VOL_UP: analogWrite(3,100); break;  //
         case VOL_DN: analogWrite(3,115); break;  // 
         case NEXT_TR: analogWrite(3,73); break;  //
         case PREV_TR: analogWrite(3,87); break;  //
         case MUTE: analogWrite(3,17); break;  // 
         case CALL_UP: analogWrite(3,73); break;  // 
         case CALL_D: analogWrite(3,87); break;  // 
         case MODE: analogWrite(3,42); break; //
         default: analogWrite(3,0); break; // nothing
        }
        Serial.println(gomb_megnyomva);
        Serial.println(digitalRead(12));
      }
    }
    delay(5);
}

int gomb_bekeres()
{
  r = analogRead(A1);
    if (r>=963 && r<=966) return(VOL_UP);
    if (r>=977 && r<=980) return(VOL_DN);
    if (r>=897 && r<=900) return(NEXT_TR);
    if (r>=935 && r<=938) return(PREV_TR);
    if (r>=887 && r<=890) return(MUTE); 
    if (r>=911 && r<=914) return(CALL_UP);
    if (r>=927 && r<=931) return(CALL_D); 
    if (r>=999 && r<=1002) return(MODE);
    if (r>=410 && r<=414) return(MODE); 
  return (0);
}

Why not work my pioneer with pwm????
