The WY-13-BT2 Bluetooth GPS receiver from Weiyang is an extremely simple device that will not attract the attention of power users. The WY-13-BT2 brings wireless navigation to mainstream PDA brands, handheld GPS navigators, and smartphones such as the iPAQ, O2, TomTom, or Sony Ericsson. There is no SiRFStar III GPS chipset inside - instead, an ultra low power consumption chipset from Nemerix will drive all GPS functions. Its rechargeable li-ion battery is capable of providing up to 20 hours of power before running out of juice. More features are available after the jump.
