I'm sorry to disappoint, I haven't done mine yet...
I just keep looking at my beautiful dash that fits together so tightly, does not rattle at all, which doesn't have any scratches on it, and thinking of the damage I could possibly do. I'm not too worried about the actual install of the auxillary input, I have a lot of faith in Jazzy, and not to mention my own abilities. I just hate taking apart dashes, those little plastic toggle thingies never quite hold as tightly, and I'm always scared I"m going to break something when I have to pry.
Not to mention, I have been pretty busy. I finally got my Lowriders and my bike racks up on the car last weekend. Lowriders are so much better than q towers. However, I need to stand on a stool to get my bike on the car. I'm trying very hard to prevent myself from immediately ordering a hitch and all the good toys that could slide into it.
I'm thinking/hoping I might bite the bullet and install the auxillary input this weekend - I had to dig out my cds to listen to in the car, and have been borrowing audio books from the library (I usually go up to DC for the weekend which is a 4 hour drive roundtrip, so I would love to be able to use my iriver.)
You guys should aplaud my restraint, I've managed to refrain from typing all the cool things about my car and what it can do, and stay mostly on topic.
