It looks like after only three months Sanyo is already bumping up its Easy Street series with the release of two new models -- the NVM-4050 and the NVM-4070. Both devices feature a 4-inch touch-screen, North American and Canadian maps preloaded, support for playback of MP3 and WMA audio files via an SD card, a headphone jack, and 2GB of internal memory. Additional features specific to the NVM-4070 are real-time traffic data via a separate subscription to the Traffic Message Channel, Bluetooth, built-in FM transmitter (so you can listen to all your stored tunes through your car's stereo system), and the ability to view JPEG images and MPEG4/DivX videos. Both devices should be available come April.
