The remote's design includes an oversize play and pause button, track-skip controls, a switch to dim your iPod's backlight (for night driving), and a shuffle-mode control. Each of the buttons includes raised markings and is formed in a unique shape to help distinguish it from the others without requiring you to take your eyes off the road.
The in-car iPod dock that comes as part of the TuneFlex Aux kit is made up of a standard cigarette-lighter plug, a 5-inch flexible shaft, and an iPod connector that can be fitted with one of the eight included iPod and iPhone adapters. The very base of the dock includes a volume adjustment knob and 3.5mm line-out jack that, depending on your car stereo, can be coupled with the included 3-foot line-input cable or a cassette adapter (not included). The Griffin TuneFlex Aux does not offer any FM transmitter capabilities, so if your car stereo lacks an aux input and you can't stomach the thought of a cassette adapter, then you're out of luck.
