The Harman Kardon GPS-810 which was just announced about a month ago is already on sale on Amazon and BestBuy for $600.The 810 is a high-end sat nav system from Harman Kardon that has a wide 4.3″ touch screen, integrated traffic receiver, bluetooth, and maps of U.S. and Canada with a 12 million point of interests.

One thing to note here is of course the wireless rotary remote controller which would make controlling the GPS navigation system while driving a whole lot easier.

Of course you can also control other functions with the remote such as the movie player which supports WMV9, H.264, MPEG-4, and AVI formats as wells as Windows DRM 10 files and subscriptions; the audio player which supports MP3, M4A, WMV formats, and the image viewer.

Another nice feature is the addition of audio out port so you can connect GPS-810 to your car stereo if need be.
