It's ot that I don't want anyone to "have" it. In fact I got my info from www.mictronics.de where he has sample code and schematics for a becker unilink CDX simulator. But the hassle of getting cables, building PCB's testing and writing embedded software isn't trivial and I did not want folks to think I was in the market to sell a solution. Just passing on the first hand knowledge that ipod to crossfire nav radio head is more than a connector and a pin strapped hi or lo.

Sorry it came off sounding like I didn't want anyone to "have" it.
