Changed this CD/aux port radio for the plain, base model radio. Saw website, called for advice, got part number from tech guy, ordered it. Took 10 min. to install. Overall great experience with this company. Tech guy warned that seat belt chimes and key left in ignition chimes may be extra loud or extra quiet. Mine are so quiet I can't hear them. That is OK. I,m a big boy and know to put on my seat belt and take my keys out.
