I had my Pioneer HU installed over the summer and now I am reading alot about the PAC kit, and I do not know if it was needed for my car. I know they needed the antennea adaptor, wiring harness, but I dont know if they needed to use any type of kit for the installion. I know someone can help me out with this quick question.

 

why don't you just pull the HU out and take a look?

 

Was your factory radio Bose? If so, then yes they *could have used it, but still not 'needed'. If non Bose, then you dont need anything aside from what you listed.
