It's "pre-wired" which means power and a direct input into your OEM radio
(and control of the cd changer through it) is all in there. The changer you
install will depend upon the bus in your car (typically M bus). If you go
with a non-OEM changer you may need an adapter by blitzsafe or soundscape.
NEVER settle for an FM modulator if you can do better.
