Have had the helix 5 SI gps for a few weeks. Was surprised that the screen was smaller than I expected. I have played with it a lot and am impressed by the resolution, it's really sharp. Still I was wondering if I wanted to keep it or return it to trade up. The other night I had it inside and put it on the couch and walked across the room 10 feet or so. I was surprise how bright, clear and visible all the info was. I think I'm gonna keep it.
