I had been planning on buying
the Ray Marine
unit since last November. When I went in to West Marine
to pick one up, the staff told me that just last week, a bug had been acknowledged that the touch screen
had a serious problem that Ray Marine hadn't figured out how to fix yet. So if you own one, you might want to contact Ray Marine.
I know West Marine isn't selling any more until the units have been recalled and repaired, but I see there are plenty of on line vendors that may not know about the problem and are still selling them.
The next step up is 400.00 more which is unfortunate, because I want to get Ray Marine to interface with my other instruments.
