The C320 appears to have exact same look and specifications as the C520 but only touts a disappointing 1.7 million POIs compared to the C520’s 6 million POIs. You also lose the Bluetooth, photo viewer and calculator seen in the C520. RadioShack is offering these units now for $299 in stores and at RadioShack.com.

If you are truly in the market for a Mio GPS unit, I would suggest hitting up Amazon.com to purchase the C520 for the exact same price. You’ll have access to more POIs and more features.
