Thanks. I joined AVIC411.com and found this post about a 2001 911 install.
"your car should not be optical since its an 01. You need a metra 70-1784 "vw harness" just remember that the constant and ign will be backwards on the harness so just hook your red to yellow and vice versa. 40-vw10 is the ant adapter you need and speed sense should be the top pin on the same side as your ground. next you will have a small square plug with 6 wires in it. the 2 center pins are amp turn on and signal ground and the 4 surrounding wires are your hot signals. cut this plug off and solder rca's sharing same ground and hook amp turn on to you guessed it, amp turn on. "
I'll search for the METRA harness and post the results.
If you could post the wire connection diagram from the D3 to the 968 I would appreciate it. I have no idea where in the harness I can find reverse light voltage, speed sense wire etc. The speakers, antenna are no problem, it's just the "GPS" wires that puzzle me.
Where is the best place to mount the GPS antenna on a cab??
Thanks

You can do a search here for the wiring diagram for the 968. I think the key word was "radio wire" . I did the bypass mod which allows me to use the nav and video functions while on the go. So this is what I did:
I relocated the mute wire to the upper right position (

Ground the mute wire (yellow black) and the parking brake wire (light green).
Connect the reverse wire by tapping to the rear parking lights.
I did not connect speed pulse sensor wire as it is not needed.
I mounted the gps antenna on the dash (center in front of the vents).
