This is not the EXACT same kit that I used (This is the newer version that supports navigation head units) but it's from the same seller, and it's now the only one they offer.

I have mine coming out of my center console so the iPod can rest neatly inside a cupholder or under the coin tray/cigaratte lighter area. PM me if you want pics of the final look, though I won't be near the Solara for the next two weeks as I'll be on vacation in Connecticut...
I can control my iPod using the fast forward, rewind, skip forward, skip back, and scan buttons on the head unit, or control it on the iPod.
The text from the iPod screen will not display on the head unit, at least not for me (Gen 1.5 JBL Single-CD) but I've enjoyed the amount of control that this kit gives me, and it charges the iPod as well, so it's never dead. Also, a good feature - It turns off your iPod when you shut off the car, and turns on and begins playing again where you left off when you start the car back up.
Best of luck with this worthwhile mod!
