ALPINE &
JL Audio make factory integration/sound processors
that allow you to maintain the factory look & feel.
how ever those units arent entirely necessary to preserve the factory
steering wheel controls, if you use an after market head unit you
can STILL integrate (aka use and/or reprogram) the steering wheel
controls using
PAC-Audios Steering Wheel Integration Interface (its
easier that the description makes it sound).
for security reasons you Might prefer the factory radio, connected to
one of the pre/processor units (links above)...or you can go w/ a
completely new aftermarket (removable) head unit.
either way you can STILL add your own BETTER AMPS & SPEAKERS.
