Amazon is offering the SkyDock In-Vehicle Satellite Radio and FM transmitter for iPhone and iPod touch for only $6.58. That’s 95% off it’s list price (because it has been discontinued by the manufacturer). It features a PowerConnect FM Transmitter that works through your vehicle’s radio with easy do-it-yourself installation. It has a flexible stalk that optimizes placement in your vehicle that works in portrait or landscape mode. It also lets you discover new music, tag for later purchase from iTunes and expand your personal music library.
note: Even if you don’t use the satellite radio service, it charges a 30-pin iOS device and has an FM transmitter.
