hi guys, I tried to install a CD-RB20 AUX attachment to my Pioneer 6850 but it at first wasnt being picked up by the head unit. I thought i mightve connected the battery line to a disconnected line so i connected the grounding wire to the head unit one and attached the battery line to the head unit battery line. I went to start the car and i get no power from the head unit at all. I disconnect the RB20 and put everything as it was and still no power to the head unit. I checked every connection i could think of and it all seemed fine. I checked the head unit fuse and it was fine, as well as the RB20 fuse.
Many times during testing the headunit continued to turn on until i connected the battery lines together. Anyone have any ideas? I think there was a slight spark noise when i turned the car on when the battery lines were connected.
In desperate need for help as its the missus' car and shes freaking out!
cheers.
