I recently went to the Crutchfield website, looked around and finally hooked up with one of their sales associates for an online chat.
I had to know about my audio system: monsoon, bluetooth, etc in order to pick out correct system for car. Got info from accessory codes on glove box door.
Anyways, we agreed on what I wanted and I ordered a radio with GPS and a backup camera along with some more features. Wires, adaptors, to retain steering controls, factory chimes, etc also included.
Delivery expected in a few days but probably will not instal yet as I am on 1st week of knee replacement recovery.
I will post pictures, if you would like.
