Okay, this arguement is going to stop right now.
Youngdoog:
Here's a dumb question; do you need to re-code your stereo? I have my doubts if many of us have done this ourselves--no need to since most of our stereos are not stolen, and thus don't need to be reset. If you do, I know of a couple of places that can do it for you (sorry, small fee will be charged, not $100).
If you don't have to, why are you bothering the dealers?
After you remove the radio, you have to flash it with a code reader. It removes the previous code, and it switches to the next code. There is a procedure to return the unit back into the car. This is only for the Nakamichi system, but the Pioneer should be a plug and play unit.
