Update: So far the antenna extension cable cale in and 3.5mm stereo cable. I'm waiting on the 5v cigarette power cord to come in. My car kit came with one but I left it in my Jeep when I sold it for the bimmer (doh!).
In the mean time, I was playing around with the extension cable and the male end fits into the sharkfin cable end. My cale sharkfin has two cable so I just need to figure out which one is which.
Everything should be in this week so hopefully I can get to the install over the weekend.
