+2 same here. matter of fact I don't remember seeing anyplace to install the puller.
Well, there are two holes, in the steering wheel frame, for some 'hooks' to go in. I installed the new steering wheel today, it took less than 15 mins (and that's with walking back and forth to the garage to get the right sockets (it is actually a 13/16", 21mm just has too much slack and I didn't try a 20mm. Come on, it's proudly made in Arlington TX it says pn the door.).
Anyway, that "Autozone, GM compatible steering wheel puller", ... yeah that one didn't fit... so I had to resort to Steve's wiggle method. With a little bit of an "Autozone pretend/induced roadrage" attitude, it came off in like 2secs flat. (Thanks Steve!!, for that tip.) I watched a youtube video up front, they showed using an Allen key, and if the other side snaps back in again... didn't happen, I put a "trim pry tool" in the side that came loose first. Putting 'everything' back together was real easy, and no surprises when I started the car.
It looks cleaner (of course it's new, my old one had the black rubberized stuff worn off). The radio controls seem to work. Phone button indeed mutes, (I think it's more like, phone button switches to a different input). The src button, changes src indeed, but when it gets to the FM/AM radio, it also goes through all the channels. (My GC has separate buttons for that).
I like the looks of it and when you're used to steering wheel audio controls it's a must have (I have been catching myself reaching for them (my Grand Cherokee has them). The price is a little stiff ($197.50 incl shipping), but hey ..... you at least don't look stupid, in front of a passenger, trying to push buttons that are not there.
