upstate,
The Becker 6-Disc CD-Changer (model number 2660) works perfectly by itself, no fuss, no muss. Just plug it in and it works. You don't even have to run additional power to it... it's in the cabling with it and is switched on through the stereo unit.

I would check on e-Bay or with
Becker North America for any more 2660s that are reconditioned (they come with a factory warranty after all).
Infinity,
The main reason I don't want a HK Drive & Play is the extra 'clutter' and controls on the center console/dashboard. Plus the way you describe how the HK Drive & Play works is EXACTLY what I have now... WITHOUT the HK Drive & Play. I just control the iPod from... well... the iPod. As long as I have a CD in the changer and it is playing there is no break in audio. (I personally just leave it repeating the same track over and over.)
I also do NOT want to shout out to thieves "Hey! iPod in here! BREAK MY WINDOW and look for it!"
Not that I'm really that worried about it... but you don't leave an iPod Video 60GB laying in plain view or show that it's even hooked up to the car.
Also, I wanted the ability to play CDs that I may pick up on the road without dragging out my laptop to rip them to MP3.
Lastly, no other changer control box will work with the OEM Becker stereo in 2004-2006 Crossfires that I know of or Becker of North America, nor any of the dozen high end shops I spoke with.
Becker is the ONLY unit that will work with Becker... and there is just not the demand for it yet, so companies like PIE (
Precision Interface Electronics) do not have an interface for it yet. Otherwise we would be able to get an iPod to work VERY easily.
In the next few days I will pull the head unit to take pictures of the cable hack I did as well as draw up a diagram for the pinouts. I have ordered the MPSS-2 from PIE and should receive it soon, although it is mentioned that there has to be a +12VDC trigger for it to switch inputs, so I'll be doing more diagnostics on the Becker iPod Remote Kit cable and see if there is some signal that is 'on' when the iPod is connected.
