China's Xiachao may not be the most well known manufacturer of GPS devices, but it looks to be keeping up with the current crop of virtually indistinguishable GPS units just fine, at least if its new GPS4305 model is any indication. All the specs you'd expect are here, including a 4.3-inch display, SiRF Star III GPS receiver, a 400MHz Samsung 2440A CPU, and an SD/MMC slot for further expansion. Slightly less common is the device's support for a rear view camera, although it's not clear if that's actually included as standard or simply available as an accessory. No word on pricing or availability, although we're sure you'll be able to find an acceptable substitute if you can't get your hands on this one.
