Okay so I'm sure this has been asked a lot, but I can't find the info via the search function... this is my first post here too.

I have an '08 GP and I don't have Monsoon or anything, I just have the factory headunit with XM already installed by the factory... every writeup I have seen so far is for Monsoon...

I just need to know what parts I need to do this jack install and if you have a link to a writeup that would be awesome! Thanks!
