Defjef,
I have the E120 and it does have a grid option. Don't like it, I turned it off.
My unit was blinking off right out of the box. The yard who did the install gave me a loaner (they do about 50 installs/yr on this unit). I had to update the software because the loaner would not read my new chart card. The update was flawless and easy. Today my unit came back and we will see.
Having used a Northstar 961XD for 9 years I can make some comparisons.
The 10 year old unit had a full on computer mounted below, the ray does it all in the dash.
The Raymarine unit is a little better in some of the
route following procedures. The latest software update allows one button track following and
autopilot engagement. One button track restart and a few other nice features. Overall the E120 is not much faster scrolling but handles other transitions with a bit more grace.
The old unit took me over 19,000. nm and I never thought that the transition to the Raymarine would be so easy. I didn't need to read the manual but I do have a good understanding of piloting and
navigation.
By the way, my Northstar backlight failed right out of the box too, except that it went totally blank instead of the two second blank outs that the E120 did. Over it's life, the Northstar required several
hardware and software upgrades including a new motherboard and hard drive.
The guys at the yard said that my service life with the Northstar was unusual and they had many problems compared to only one issue on the Ray E120. The only reason that I switched to Raymarine is that Northstar built in an operational end point and would not update the tides and currents, I said by-by.
All in all the Raymarine is simple and reliable.
