Summary: We needed a GPS for the truck and boat and this was the best price for a trusted name. There is a lot to learn about the unit, but once we used it a few times it's pretty easy to use. The sound quality is pretty "tinny" but it can be played through the car sound system so that's no biggie.
Summary: We purchased this unit on July 16, 2007 for a motorcycle ride from Minneapolis, MN to Anchorage, AK and it worked great. Normally we would use the Alaska Milepost magazine to reference the route, but the iWay 600C performed so well, we never used the magazine. My only problem with the iWay 600C was that unit came with a 2003 database and some of the locations and roads had changed. An updated database is available from the iWay website, but it costs an additional $75.
Summary: I've had the 600c for a couple days now and ran a comparative test against the Garmin GPSMap 276 with the automotive kit. Both units have their strengths, but the 600c has a larger screen and fits on the dash of my 3 vehicles a lot better. The 600c is much simpler to use than the 276 because of the touchscreen capability which the Garmin doesn't have. The 600c gives up a smidge in screen clarity, but it also provides satellite imagery which the Garmin doesn't.
