I too like to buy my GPS software rather than "rent" it. I already had a Garmin GPS 10x when I got my Tilt. It works extremely well and is so sensitive that the tiny GPS 10x receiver can be in your pocket or in your glove box and still work just fine. I will probably get a Garmin XT sometime soon so I won't need to carry my 10x, but I will wait until Garmin puts it on a larger microSD card. Right now I would rather have my 6 gb microSD card and the Garmin 10x in my pocket than the garmin XT on the 2 gb microSD card that comes on now.
