I also had them replace my old 276C that had been all over the place. The screen had started getting dark lines though it. They sent me a refurb that started shuting itself on and off on my first trip with it to California back in '07. I had contacted them via internet during the trip and tried stuff the rep told me. He told me to send it back when I got back home. Witch I did and they sent me another. I probably have about 80,000 miles on this unit and no problems. I just did get another one off ebay for a spare for when this one goes out. But, I'm not spending 70 bucks to unlock the code ;-) So, it will stay a spare. ;-( . I bought a Zumo 550 and it sucks after being spoiled by the 276C. If I can fix it with this touch screen replacement, it's going on ebay.
