Bests & Worsts Reviews from Amazon

We are moving to another city where my wife definitely will need a gps. After reading reviews, I bought a refurbished 255w. It worked great except the speaker. The speaker seemed to be damaged. Not just robotic, but sounded mechanically damaged. I repacked it last night in order to return it to Amazon. But, I will buy another 255w, hoping to get a better one. Probably, not refurbished one? Update. I recevied a replacement from Amazon.com. This one looks way better. Amazon refunded my shipping cost. The new refurbished unit doesn't have the problem the first had. The first one had all favorite info of someone else, but this replacement seemed to be reformated and had a color sticker on the screen. It looked like new. In addition, I could download a new 2010 map right away. (Which the previous one did not provide me.) Now, I feel better.
