Summary: The display is very large and easy to see, even in broad daylight. The software is intuitive and fairly straightforward. Though the touchscreen seems less responsive to those that own a smartphone or tablet, it does the job. My only complaint is that we periodically have to buy updates.
Summary: This reminds me of my cell phone. I fought for the longest time against it as I did not need it. When I finally did get it I found I couldn't live without it.This item is not only a convenience and a essential road aid it is a downright safety device.
Summary: I purchased this product in 2010. It has performed pretty well for 2 years, but is in need of a map update. The software was updated about 3 months ago (more or less). I found I was unable to get the update using my mac so I borrowed a friends PC. The update was very slow!
Summary: Exactly as expected. Gave 4 stars on Ease of use because we also own a 550, and it has better menus (but was more expensive.) Very good product. We pull a 40' horse trailer, and the lane guidance is extremely helpful. Highly recommend.
