Summary: The main problem I found with this GPS was the slowness to capture the GPS signal. Somethings it takes more than 2 minutes to find the GPS signal. Mio also stopped to update this GPS, so you cannot update the maps inside anymore unless you unlock your GPS software and install some other vendors software
Summary: would have been nice to get the software with it that came with the unit when it was bought new...i din't need the unit, i needed the software to use on the one i already have. now i have 2 that i can't use....
Summary: Mio C520 GPS menu is somewhat cumbersome and I've had occasions where I too easily pressed the wrong command. It is sometimes slow in re-calculating if you miss a turn and you'll have to think a little like a computer when you listen to its instructions. It is probably the same with any GPS devise but I would use it more as a supplement to a map than a replacement.
Summary: I bought this GPS about a month ago. Acquisition time, route calculation and recalculation times are excellent. My previous Gramin took forever to find POI's and calculate and recalculate routes and this was the main reason for purchasing the new GPS. Routing is OK. I discovered a few errors in the maps in the Boston area but nothing that will make it a deal killer.
Summary: The first C520 I purchased had a power supply problem (probably with the DC cord) and failed within a few hours of use. The replacement has not exhibited any of those problems. I purchased the Mio because of it's larger screen size and lower cost. Many skins are available online, so you're not stuck with the format the manufacturer devised. I've tried several of these skins, but none give a bigger view of roads and locations like the Garmins and Magellans.
Good for major cities...not so wonderful for the rurals

Summary: The Mio C520 is overall a pretty good GPS Navigator. I recently moved from WA to MN and used it in harmony with AAA Triptik pretty well. A few negative points were that if you didn't hit the exact spot that it believed to be the via point, it would continue to try and route you back to the via point for several miles or until you edited the route and removed that via point.
Summary: This GPS works fine, BUT you have to buy $75 map updates for it. I have never written a review before but I wanted to share my frustration about MIO's cust service and their map update policy. I will not purchase another of their products!
Summary: Not that user friendly. I'm living in bay area. It lost me several times. I seldom need to use a GPS.. more correctly .. never! I always look at the google map and I know how to get there, but this GPS is really confusing sometimes. Moreover, I don't like the text-to-speech content...for example.. instead of calling 101 - highway 101, it will say bayshore highway. and 92 will be another name that I can never remember cause no one here will use that.
Great GPS but version 2006 MAPS on a new GPS like this one is not good

Summary: While this GPS is fantastic, I was surprised that it came with version 2006 MAPS which are 2 years behind. Shame that it comes with old maps. You will need to pay around $50-$80 to get new maps.
