I just had something interesting happen to me. I bought a GPS on Amazon, and I tried doing a map update (every Garmin comes with 1 free map update) and it wasn't working. I called Garmin (their average hold time is 30 min!) and they said the device isn't eligible for an update bec it was first activated 1 year ago (the map update must be done in first few months after purchase). I called Amazon and they said they would refund me for the GPS. I was very surprised to buy something from Amazon, to find out later that its used and not new!!
