with the great disappointment from the Garmin c330 DOA , out of the box and immediate satisfaction come with this tomtom 300 unit . it have many language , voice , and great shortcut for local road . this unit have a durable support arm , easily usable touchscreen and simple route instruction with mode to tailor the route to eliminate ie : toll road . the voice prompt be highly accurate and hold true to instruction within 100 ~ 200 yard . I be still figure out the compass and car speed and why they be not there on the screen . the unit take sd card and I believe some can be order for other area . overall , I be highly impress with this .
