I'm selling my once used Garmin Oregon 600 GPS unit. Large color screen. 7.09 Oz with batteries installed, can be less with lithium batteries. Full disclosure and honesty in what you're buying, I had issues with it randomly shutting off or freezing when I installed my OnXmaps chip into it, or maybe it was the unit itself. I don't know, I don't care. There are other reviews out there describing the issues, but maybe someone more competent than me can fix it, get Garmin to fix it or upgrade the OS. Other than that, I love the unit, its accurate, bright, colorful and works well. It sells brand new for $300, I'll take $75. Not bad for a brand new unit.
