Doubleadesign, I ordered the X3 input adapter. (This will let me keep the CD player). I'll post pics as soon as I can. Unfortunately, I own a Trooper, not a VX. So, the radio removal procedure will not be the same, but the radio will be. I'll post pics likely by next weekend.
Perhaps somewhere else on this group there are instructions to extract the radio?
Also, this may present a challenge: This adapter needs some space to hide inside the dash, my chosen location will be somewhat different than yours.
If you are certain you want to stop using the CD player, you can go ahead and order the PIE TOY-AUX; I have tried it and it works. If you want to keep your CD player, (like I am doing), I'll let you know how it works out with the X3 when it arrives.
Also, in order to reduce the risk of a rattle, I am wrapping the loose connector and the converter box in the middle of the adapter with single sided sticky foam tape. The best way to get this is to go to an auto parts store and ask for a roll of "Foam Camper Tape" used for sealing a Camper to the back of a pickup. It costs less than $10. Be sure to buy the kind that is only sticky on one side!
