I just realized that Harman Kardon has satellite navigation device too, previously i recognized the Harman Kardon as a well known speaker manufacturer for laptop. As this post written, the Harman Kardon GPS-510 is already available for pre-order at Amazon.com.
The new GPS-510 sat-nav is preloaded with U.S. and Canada maps and coming with voice guidance, 4-inch touch screen, and SD card slot. Beside its main functionality as a satellite navigation device, this device also offering multimedia features such as music and video player.
