Garmin Radar-overlay possible???

[Hewesfissher]

I was working with a 4212 unit last week and wondered why I couldn't get the navigational chart overlayed with the new HD Radar video painted atop it. I also tried on a 3210 last month....to no avail.

I was thinking that maybe it could if I had a heading sensor, but didn't get that impression when I walked through all the menu options.....

I just installed radar and the overlay worked fine even without the heading sensor, I do think you need to be going at a decent speed though

I looked at the manual again and found the page where it talks about it. Maybe i hit a wrong button. It says it does do it, Im glad I revisited the issue. Page 42 in the manual.. OOps.

Thanks guys.

You won't have the option until the chartplotter can see the radar. This is probably a connector or power problem.

4210 w/ gmr 18 HD overlay works fine on mine, no heading sensor.

Select Charts, then "Radar Overlay". Do not display a Nav Chart, then try turning on Radar Overlay, as you would do on a Raymarine unit. In the Garmin, you just select the Nav Chart called "Radar Overlay" which is of course, a nav chart with radar overlayed. I should translate for the Chineese!!!

You know: "Red button = Push this button to activate the function of the red button."

You know BIRDMAN- You nailed it. Thats what the problem was....VERY different menu system.

I can see where moving between one guys menus to another guys menu is a bit difficult.

Yep, took me a few minutes to figure this one out too. But at the end of the day, the Garmin menu's are 1000 times easier to operate. Especially with the touchscreen.

I guess after messing with a 4212 unit, I have found that you cannot have a chart with overlay on while you have a ff display too.
