Back in May, we reviewed the Mio C220 portable navigation system, which we loved for its ease of use and affordable price, but ultimately we had to diss it because of an awful screen. Well, we're happy to say that its successor, the Mio DigiWalker C230, offers the same intuitiveness and budget-friendly price plus an improved display and text-to-speech functionality. It's rare to find the latter in an entry-level GPS device such as the C230, so that's a nice surprise and gives it an edge over its competitors, including the Garmin Nuvi 200 and the TomTom One. Our complaints are minor, having to do mostly with the design; for example, the extreme compactness of the device makes it a bit difficult to interact with the touch screen. However, if you're looking for a very basic navigation system or are new to GPS, the Mio C230 is a good choice, especially with its $250 price tag.
