Just take a look at this - "Navigate maximizes convenient control of your iPod. It has control buttons your fingers can easily locate by touch, and it restores the tactile feedback of the iconic click wheel to touchscreen models. (Which comes in pretty handy when you’re using it in a car and need to keep your eyes on the road.)"
Well, I guess there are too many people who can't decide what to do - drive the car, or use their iPod/iPhone, don't you think? After all, as far as I know, most cars come with some MP3 player/FM tuner built in these days, but...
..."Navigate gives you a generous OLED information screen (for when you need to glance at it), on/off, play, volume and EQ controls, and an FM stereo radio. Tuck your iPod out of sight, but keep controls close at hand. iPhone users: Just plug Navigate into the dock connector then connect any 1/8†(3.5 mm) stereo-mini headphones (including Griffin’s TuneBuds Mobile) to listen and talk."
The product compatibility list is pretty long, including most iPods since 2005 and, of course, both the iPhone and iPhone 3G.
Priced at $59.99, Griffin's Navigate could be a really handy addition to your arsenal of iPhone/iPod accessories, but you'll have to wait until March 2009 to get the iFM app for it.
