Pinout for Audiovox XV6600 PDA to iPAQ 3950

[FlyGrumman]

:?: I need to get the pinouts of the Audiovox XV6600 PDA as well as the 3950 iPAQ.  I need to build an adapter that will allow me to use cables built for the iPAQ 3950 with my new Audiovox XV6600.

I use an aviation navigation system and the cables were designed for the 3950.  I'm hoping to use it now with my XV6600.

Any help would be appreciated (especially if someone wants to build one and sell it to me)!
