Looking to source some interfaces that would help getting the reverse camera fitted and being able to play from iPod with the option to control from steering wheel buttons (next track / prev track, etc) an not through the AUX stereo jack, also being able to charge the iPod.   I've purchased the NavTool at a very good price from ebay, made an offer of $150 which was accepted and should get it quite soon, it says it landed in UK already.   2009 Nissan 370Z Navigation Video Unlock Adapter Add D
