...Any recommendations? 1- What equipment do I need? Know the price?
2- Should I try to install it myself?

I would think buying the equipment I need online and then taking it to Best Buy would be best. I called Best Buy and asked how much the equipment plus installation would be and they said around $325.

wow your bending over for 325 buy one of those adapters you play through the radio or get something from crutchfield they are pretty good with install help
