In addition to the TN700 presented at CES 2010 by Motorola, they also displayed a less-powerful version of the GPS codenamed TN500. One of the main differences when comparing the two devices is the screen size, while the TN700 is bigger and has a 5.1-inch screen, the TN500 features a 4.3-inch touchscreen.
Anyhow, the rest of the features are pretty much the same in the two devices: it has multiview so you can see different information on the display screen like the route + the points of interest + contacts + other details. Another good detail is that you can perform a lot of actions, like making a call or search for a contact, always without using your hands - only your voice.
The Motorola Motonav TN500 will be released in the first quarter of 2010.
