Mio DigiWalker C520

We found the most exhaustive reviews of the Mio DigiWalker C520 at GPS Tracklog and GPSLodge.com, where testers describe how every feature performs during lengthy road tests. PC Magazine helpfully compares the Mio C520 with other mid-priced widescreen models, but the comparisons are scattered throughout reviews of the various models. CNet.com also does a full road test, although the mixed results don't seem to justify the high rating CNet.com gives the unit. About.com names the Mio C520 to one of its "top budget picks" lists, but the rankings don't seem to be based on any testing.

More than one reviewer notes that the Mio DigiWalker C520 is particularly slim and attractive, and it probably offers more features than any other unit in the price range. Features include an MP3 player, Bluetooth, and a wide screen that can go split-screen, showing the map on one side and helpful navigation data on the other. The Mio C520 has the ability to speak street names ("text-to-speech"), which its competitor the TomTom ONE XL (*est. $195) lacks. Testers get mixed results with the Bluetooth: Some have no problems, while others find it crashes the unit or won't work even when it's paired properly with a phone. Although the Mio C520 navigates well in most tests, some testers find glitches - the unit locks onto satellites slowly or can't recalculate a good route when testers veer off course, for example. Reviewers find the Mio C520 isn't as easy for beginners to use as a Garmin nüvi is, but they say it's still a good budget alternative to the Garmin nüvi 660 (*est. $345). User reviews are mostly positive, but have one major recurring complaint: Map updates from Mio cost $80.
