Hello Steve,

Its basically because the ignition key has no accessory position.  In my
cars, I've made a tap off the seat belt warning chime (terminal #85).  If
you insert the key and open the door you'll notice that the chime goes on.
The ignition lock has a separate switch to monitor when the key's inserted
(terminal# 86/S on the lock).  You can use this wire to attach to the
radio's ignition wire.  If the radio only has one fused wire for this, use
a separate relay and use the "ignition key in" wire to run the relay.  The
crutchfield guy's suggestion is not valid if you want to play the radio
with the engine off.  You'd have to turn the key to the "on" position which
also turns on the entire dash and a bunch of other stuff and puts an
unecessary load on the battery.

HTH,

-Tony
