I completed the aux input install detailed in DIY: Aux Input for Symphony II+on my Concert II+, but with a slight modification. Instead of mounting the socket in the dash I chose to route it to the arm rest. My reasoning was that I don't like a cluttered dash (cup holders, phone holders etc...) so this way my media player can be hidden away. The added advantage is the DJ (oldest daughter) can be seated in the back and still control the decks. Just fortunate she has good taste in tunes (Rock!). Pics to follow.
