Summary: I purchased this GPS approximately two years ago and have had to replace the 12V electrical cord and the back plane mount device already. I use the device while on vacation. Total times used while on maybe three dozen times. The external electrical connections are not very rugged. I had to hard wire the antenna as the fold down unit did not reliably maintain satellite connections. Think twice before purchasing.... only at a severe discount.
Summary: Magellan Customer service is the worst customer service I have ever dealt with. They offer a free 30 day map update since all of their products ship with out of date maps. This would be a good thing except it is in the fine print of their products and their customer support email address that their website list is the wrong address. I had to get through to their customer service by posting a bad review on their website.
Summary: This is an old unit. It's big. The operating system is slow. It will freeze every once in a while. Magellan is TERRIBLE about their map updating. Magellan has TERRIBLE offshore customer support. I don't care if customer service is off shore, but let me talk to somebody who is empowered to solve my problems.
But even with it's old school computer voice, and now 2 year old maps... it works and it's better than not having a GPS.
However, in 2008... get a Garmin.
Summary: Big, bulky, but not terrible. Unfortunately when I called the Customer Service people to say that all of the sudden, for no apparent reason it just doesn't work any longer, they said, "sorry, but there's nothing we can do."
I liked some of the features, but, man, if the thing doesn't work, I'm stuck.
So- I bought a Tom-Tom One from RadioShack for $150. What a deal, and way better than the RoadMate.
