The latter displays various details about your trip. You also have your choice of viewing a full-screen map or a split-screen view. Maps are presented in 2D or 3D mode, and there's a Night Mode option that automatically changes the maps colors for better visibility at night. That said, you get all the major categories-gas stations, ATMs, lodging, and restaurants-as well as more specialized interests, such as concert halls and amusement parks. The number of included POI is a bit disappointing, since even the entry-level Mio C230 offers more entries at 3.5 million while the C520 contains 6 million POI. The C320 supports multistop routes, and there's a database of 1.7 million POI. The system can create directions by fastest, shortest, or most economical route with or without toll roads, highways, U-turns, and so forth and in various modes, including car, bicycle, and pedestrian. You can start planning a trip by entering a specific address, picking a POI, selecting a destination from your My Favorites or recent destinations list or you can tap a point on the map and hitting the Route To option. The Mio C320 is equipped with a 20-channel SiRFIII GPS chip and comes preloaded with TeleAtlas maps of the United States, Hawaii, and Puerto Rico. The Mio C320 comes packaged with a car charger, an AC adapter, a vehicle mount (windshield and dash), a USB cable, and reference material. You will find a power button on top of the unit, a mini USB port on the bottom, and the speaker and an external antenna jack on the back. Once again, as with the C520, we're disappointed that Mio didn't equip the C320 with a 3.5mm jack since this would allow you to plug in your favorite pair of headphones.
On the left spine, there's an SD expansion slot so you can load your multimedia files, as well as a 2.5mm headphone jack.
But as we've noted on previous Mio reviews, however, a number of tabs on the map screen that open and hide various navigation tools require some time to learn. The main page presents you with four clear options: MioMap, Audio, File Manager, and Settings. Though not quite as simple and user-friendly as a Garmin or TomTom device, the menu system and interface is still pretty intuitive. In that case, adjusting the backlight helped the situation.Īs with the company's other models, the C320 uses the Mio Map v3 navigation software. For the most part, we were able to view the screen in various lighting conditions, though colors washed out a bit in bright sunlight. The display has a 65,000-color output at 480x272 pixel resolution, so maps were bright and easy to read. We like the sleek design (4.9 inches wide by 3.1 inches high by 0.5 inch deep 6.7 ounces) and the nice 4.3-inch-wide touch screen. The Mio DigiWalker C320 resembles its older, more full-featured brother the Mio C520 in looks, and that's just fine by us.
