See full version: GMR™ 18 HD
To help you avoid traffic on the water, the GMR 18 HD provides MARPA target tracking when combined with a multi-function display and an optional heading sensor. MARPA tracking allows you to track the bearing, course, speed and predicted closest approach of up to 10 targets. In addition, like all Garmin radars, the GMR 18 HD has self-contained signal processing, which provides you with a more precise, easy to read signature.
The GMR 18 HD features high-powered Digital Signal Processing, providing sharper radar imagery and improved target separation. more
Sharpen your radar picture with high definition performance. The GMR 18 HD radar offers a whole new level of radar scanning capability.
This 18" (45.7 cm), 4 kW high definition radar has a 36 nm range, bringing radar images into even clearer focus. With automatic pulse optimization technology, the radar matches pulse widths and repetition rates with the nautical mile range that is selected. Combine that with the antenna’s 5 degree beamwidth, and you’re looking at the best weather penetration and target definition in its class. here
The GMR 18 HD transmits data over the Garmin Marine Network, a 100 MB plug-and-play proprietary network that gives you the ability to expand your boat’s system as needed. Once connected to the network, you can use any network-compatible Garmin chartplotter as your radar screen. And as an aid to locational awareness, you can overlay the GMR 18 HD radar image on the chartplotter's map page. You also can split the on-screen display so you can view the map and the standard radar page simultaneously. more

the pairing mode is for the light so it can't be controlled from any random device near you. On the other hand anybody can connect to the radar. here
Hi, how do I pair the Varia with the second device? When I turn the device on in pairing mode by holding in the power button it seems to drop the connection with the initial head unit.
I have been using it in group rides where a person with a radar is always on the end of a peloton and other people are getting these notifications to their edge devices.
If you get the idea the NMEA-0183 standard is a bit loose. yep.
And even then, not every piece of gear understands all of the NMEA sentences. Some equipment may only detect certain functions.
The back of your Radar Display should have a 7 pin plug for 0183.
The pin functions are:
Now the problem: My Furuno unit was hooked in to the GPS but I never got any coordinate info from it. Looking at how they had it wired they had a green and a yellow and the yellow wasn't even connected. The green wire was connected to the black ground. The Furuno manual doesn't explain the breakdown of the colored wires like the Radio's manual did. It says refer to the interconnecting diagram at the back of the manual. I'm not a scematic expert and it's half in Japanese.
And when you cross mfgs, realize that there are two kinds of NMEA-0183 packets (they call them sentences). First, there are the generic or public packets which many devices understand. [links]
