At one time, I thought I saw a few people advertising on here that they were selling Garmin Nav data cards for about $50 if you would send them your outdated Nav data card. Is this a legitimate thing to do and if so, does anyone know who that was?
Craig do you have or are they the same for the 430W? I need a terrain card has not been updated in a couple of years. I also could use the other update soon.
