Ok I am stunned to discover this (very very common I would think) need is proving so hard to find. I want to wire an iPod into my car system. I want it to be center console mounted and powered. I will wire its output into the car stereos line in / aux. Simple right ?? I will wire the power supply to the cars ignition so only when the key is in the ignition will it have power (same as my stereo). I have no interest in radio broadcasting, or cassette modulators etc etc.. A line out charging dock is what I want. I also dont want to move to a head unit with iPod control due to limited head unit browsing ability. The control and playback is far better left to a well mounted iPod. However, and this is where I am finding it hard) the dock must pause the playback, and resume playback from pause, based on when the power (to the dock and hence iPod) is applied and stopped. The iPod must shutdown also once power is removed (delay acceptable but resume must work) not just sit there slowly losing battery. I have gigs and gigis of DJ mixes, many multiple hour sets, and you cant keep seeking and messing about to get to where you were. the pause and resume is the key here. The closest I have found are docks that pause, then shutdown the ipod, but none I have found will resume playback once power is reapplied. All require user intervention to resume. Surely someone makes one so that playback 'just works' right ??
