Just installed one of these in my new car and, after spending a few days driving around with it, I highly recommend it. http://us.kensington.com/html/14492.html I got a new Lexus IS250 afew months ago and had been looking for a way to interface my ipod. A simple cord into the aux input worked great, but I also wanted to charge and to change tracks without having to fiddle with the touchscreen all the time on the phone (bad idea while driving, as I soon found out). Lexus wanted $300 plus installation to get this done -- no thanks. I had seen this particular solution online, but was skeptical of how it actually performed. and how it would fit in my car (I HATE to have wires running everywhere... I like things to be hidden) However, when I was killing some time at the Apple store the other day between appointments, I saw that they had them in the physical store. Perfect! Now I could try it out and take it back with no shipping hassles if I didn't like it. I got it and plugged it in to my car as soon as I got home. It consists of a simple 12v plug with two wires: one to plug into to the dock connector on the iPhone and the other to plug into the aux input on the vehicle. Mine is installed completely out of sight in my center console. You also get a nifty remote to attach to the steering wheel. It's small, unobtrusive, and looks really sharp. Made of sort of a matte rubberized plastic that molds to the sterring wheel, with soft velcro securing around the back. It completely blends in with the black leather on the steering wheel in my Lexus IS250. I mounted mine on the bottom left side, just under the spoke with the other audio controls for my stereo. Out of the way while driving, but still easily accessible. The audio sounds great and the remote works perfectly. The only problem I had at first was an annoying buzz coming through the audio. It varied with RPM and gearing, so I knew it was coming from the car somehow, not the LiquidAUX unit. I quickly diagnosed the problem as ground interference from Lexus not properly grounding the 12v supply in the console (thanks for nothing, Toyota). Problem was easily solved by ordering a ground loop isolator from Crutchfield (http://www.crutchfield.com/S-mW61MVi7zxj/p_127SNI135/PAC-SNI-1-3-5-Noise-Filter.html) and placing it between the 12v supply and the aux input. Now it works great, with nothing but great sounding tunes coming through the stereo. Kensington LiquidAUX- $60 GLI - $20 Total cost: $80 plus 5 minutes of my time to install. Lexus cost for same functionality: $300 plus installation costs. I think I got a pretty good deal.
