Thank you, this info was helpful. I thought I could attempt doing it myself, but I definitely don't want to chance burning up the radio by doing it wrong my first time. I hooked up a Sirius radio to the back of my factory radio, but harnesses scare me. Also, driving up to the back of Best Buy with a low cut shirt didn't help get it installed either lol They only install what you buy from the store and don't appreciate outside offers. Ooops.
