VW phatbox in Honda Pilot - ideas or experience?

[bman]

We just bought a new (2006) pilot that has the head unit with an in-dash 6 disk changer, XM radio and a rear DVD player.  I would like to convert my VW phatbox to Sony and then use a PIE adapter (or other) to connect the phatbox to my head unit.

If someone has done something like this, any ideas would be appreciated!  We really miss our phatbox since getting the Pilot.  

Thanks
