The Solix platform is just more advanced and has more options for customization. You can create any view you want. Some of the cross touch features are pretty cool- if you're in a multi-screen, say for example running Side Image and Down Image at the same time, holding two fingers on Side Image will change your screen to Side Image only; once you're in Side Image, holding two fingers on the screen will take you back to the previous multi-screen with SI and DI. Swiping two fingers across the screen pops up your views; you can quickly scroll through and pick a view. If you do decide to network to another Solix down the road, the platform is powerful enough to share map cards, ie one map card can be used and share over the network by multiple Solix units; Helix units must have a map card for each unit. I'm certain there are some more features, but these are the ones I'm familiar with.
