GPS guidance systems...

tuneup

So this is pretty friggin' lame, but hey...if the Strut collective could give me some advice that would be great. I'm checking out the Garmin 330 GPS device for the long drives on those extended digging trips and wondered if any of you had either bought one, or used one at any point. Or if there is another brand and model you are feelin' that's good to know too. I just don't want to have to download anything....Much thanks...
