I was absolutely shocked at the difference between the analog and digital connections. I expected a difference but wow! I need to empty my cargo area so I can hook up the telephone interface. I was in a hurry this morning so I got the audio up only. If I remember correctly, I have to open the cargo cover and then there should be a black plastic housing that has the TCU cable in it....

Am I correct in that?
