Chalk, I bought one of those from Wally-World for about 2 days. I turned it on at the house and played with it some, then I hooked the boat up and headed to the Icky. Got the boat unloaded and turned it on, but it didn't come on. I fooled with it for a while, even replaced the new batteries with brand spanking new batteries to no avail. I finally gave up and went fishing.
On the ride home I picked it up and hit the power button and the dad-gum thing came right on

. If I didn't have about $200 in that thing I would of seen how big a dent I could have put in one of those street signs

.Needles to say I took it back the next day, then went to West Marine and bought my Garmin 76.
I'll never buy another Magellan, but thats just my two cents.
