Mio C220 review I've been trying out the Mio C220 for the past couple of weeks, and I am convinced that it is a great value. Currently available for around $185 $165 (and the price may drop even more between now and the holidays), this unit will likely be one of the market leaders in terms of budget car navigation systems. <a href="http://adserve.bizrate.com/pp/content/tal/publisherID-3986/assetID-723/assetTypeID-9/placementID-16/showProducts-2/showRandom-0/start-1/sort-default/cache-1/noLog-1/noScript-1/onlyOffers-1/categoryID-11210000/tokenID-7X/keyword-Mio%20C/style-">BizRate</a> The Mio DigiWalker C220 has pre-loaded maps of all 50 United States, a 3.5" touch screen, SiRFstar III chipset and over 3.5 million points of interest (POIs). There are no frills here -- no MP3 player, Bluetooth or text-to-speech (so you'll get "turn left in 200 feet" instead of "turn left in 200 feet on Highland Drive"). For those features, you'll need to step up to the Mio DigiWalker C520. Some reviewers have complained about the screen visibility, and it's not the brightest. But I think it is generally quite legible, even in bright sunlight. It is however, difficult for me to read it in bright light while wearing sunglasses, and I nearly always wear sunglasses while driving. In the end, the screen probably is the weakest feature of the unit. UPDATE: A new unit, the Mio C230, improves the...
Switching between highway and topo maps on Garmin handhelds Oftentimes, handheld users will load both highway and topo maps to their unit. Garmin handhelds will show the highway maps by default. The highway map (City Navigator or City Select) for an area must be turned off before you can see the topo map. This is especially problematic when you have a lot of maps loaded and you don't know the name of the map for your current location. In the past, I've laboriously scrolled through long lists of highway maps, deselecting each one until contour lines appeared on the map. But there is a simple solution. The instructions below are for the Garmin 60CSx, but I'm hoping this works for the eTrex series too. Perhaps someone can verify that and comment below. From the map screen, press Menu, then Setup Map, and scroll over to Map Setup - Information. You'll see your list of loaded maps with a check mark next to each one. But rather than de-selecting them one by one, press Menu again and you'll see two choices - Hide City Select (or Navigator) and Hide US Topo, as shown in the image. Pretty cool, huh? Thanks to Hogrod on Groundspeak for this tip.
