Azentek SmartMirror SM-450 Released at 2008 SEMA

Since the GPS navigation devices market is a highly competitive one, the only chance for a startup company to actually hit it big is to come up with a design and features few others offer. And that's exactly what the people over at Azentek seem to have achieved, since their SmartMirror is capable of doing no less than three things at a time: display the road ahead (GPS routing), the road behind (rear-view mirror) and even take calls, via the built-in Bluetooth module.
The SM-450 is accompanied by 64MB of internal memory, which are used for running the Windows CE .NET 4.2 embedded OS and the Navigon Mobile Navigator 6.5 navigation software. Storage is provided by a 2GB SD card, while the maps are displayed on the built-in 4-inch touchscreen TFT LCD.
The device also sports a 16-channel GPS receiver and offers a host of very useful navigation options, such as Lane Assistant and Reality View for extra guidance, spoken street names via text-to-speech, intuitive menus and 2D and 3D maps as well as easy-to-read map views that adapt to the driver's needs. Plus, it doubles as a Bluetooth speakerphone (via the built-in Bluetooth module), displays the incoming calls on the screen and supports Manual/Auto call answering.
It has a MSRP of around 800 US dollars, which is way above the average price range for the PNDs offering the same specs and functions.
