LAST EDITED ON Jun-12-12 AT 02:05PM (MST)[p]DBLung---They are great as I have the Wyoming chip. What is really cool is that the company will now upgrade them the first year for free, including where it will now work on the computer at no extra cost. I'm getting ready to send mine in for the free upgrade. With the chip in the GPS there is no way you can stray onto private property any longer without a paper map in hand. PS: The microchip also comes with an insert that will let you use it in your Garmin GPS mounted in your vehicle that takes the bigger chip. They really thought of everything and they are a little pricey, but more than worth it when you figure what a trespassing ticket would cost.
