Thanks for the information... Do I read correctly that the Blitzsafe adapter fits into the CD changer wiring? I don't have a CD changer, how do I tell if I have the wiring - 3 pin, 6 pin, etc...

Also, really like the possibility of getting a 2003+ head unit to make use of the Aux input. Nothing on ebay at the moment - any idea where else I can pick one up.
