I would have to agree with SD. I was going to get the new Helix SI, could not wait till the store had one. well then I looked at the screen size and changed my mind. Glad I waited, Now I can get the helix 7 for a few more dollars... but still thinking about the 8 series.
All I know for sure, Is when you have a 5 inch screen and 7 inch screen, the money will be well spent on another 7". I will put the electric motor down and turn on the Elite 7 (color) and tilt the screen so I can watch that one on the bow, instead of the black and white 5" screen right in front of my steering wheel. I'm definitely done with 5" screens.
