According to Gerhard Mayr, Vice President of Worldwide Mobile Phones & New Markets for Navigon, "The iPhone is the most elegant smartphone available, therefore a mount should never get in the way of showcasing the design." This kit from Navigon is a more stylish rendition of German tech design with a "barely there" look.
The mount is easy to fix in any position on any surface in your vehicle which reduces distraction to the driver and also places the iPhone in a position that is optimal for a GPS signal. The included car charger, as well as the 5-foot long connection cable, are perfect if you need to use your iPhone's navigation system on long trips or vacations.
It appears that the physical cradle could fit other devices besides an iPhone. However, if you buy this kit and you do not have an iPhone, then you now have a 5-foot long iPhone cable that you do not need. The charger, however, is a simple one that plugs into your lighter jack and has a USB port on the other end making it universal with practically every smart phone on the market that uses a USB charging system.
My point is that this case, while designed for the iPhone, would be good for most smartphones out there or even smaller GPS devices. The Navigon Car Kit is available now for the iPhone 3G, iPhone 3GS and iPhone 4 for a market price of $49.99. However, you can get an introductory price of $44.99 if you purchase one before February 3rd.
