Harman Kardon is a fairly new player in the GPS race, and it looks like they’re starting to gain a lot of attention, especially with their new “Guide + Play” series. The company is adding three new models–the GPS-310, GPS-510, and GPS-810. Each has a 4-inch widescreen display (except for the GPS-810, which has 4.3 inches), text-to-speech functionality, 2GB of internal memory, and GPS and PMP features. The GPS-510 has additional video options, real-time traffic info, and SDHC card support. The GPS-810 has an FM transmitter, a wireless rotary controller, and built-in Bluetooth for hands-free calling. The Guide + Play GPS devices from Harman Kardon are going to be available next month, with the GPS 310, 510, and 810 selling for $350, $450, and $600 respectively.
