The 300 has an extra feature that will allow it to use just about any USB power adapter that the 200 does not have. It is called Spanner mode. I have a 200 and had to buy a Garmin power adapter to power my unit in the car. I got it from GPSCity for about $18 so that is not too bad. I needed to order the cradle also so I went ahead and ordered it. I will say that the screen is a good bit brighter using external power which is nice.
