Ah sorry didnt give much detail there! It goes into the back off the Pioneer Appradio. What I had trouble with was how to route the cable to the back of the headunit from either the area by the air con display or even up by the windscreen
The best place I have found is the section in which you removed the top stereo anchor bolts after you remove the panel below the air con display, just stick it in there. A lot of guys have used this area with success. Had my appradio installed for a month now and I have never lost satellite signals.
No need to take anything apart further apart once you have accessed that area, look towards the back of the section (closest to the air con display) You will see a hole, drop the lead into this area and you will see it appear right behind the stereo area.
