Satellite weather for apps and portable GPSs

Nothing beats SiriusXM Satellite Weather for making smart in-flight decisions, and the GDL 51 makes it easier than ever to view this high quality information on your tablet or portable GPS. The compact receiver sits on your dash and streams weather, SiriusXM Radio, attitude information, and GPS data wirelessly via Bluetooth. The built-in five-hour battery means it’s completely portable, and perfect as a backup too.


  • Weather is delivered by satellite, allowing reception at any altitude, anywhere in the US and southern Canada
  • View high resolution radar, lightning, satellite imagery, METARs, TAFs, TFRs, echo tops, Pilot Reports and more
  • Listen to SiriusXM Radio in flight, with over 150 channels of music, sports and entertainment
  • Attitude heading reference system (AHRS) is a backup attitude source
  • Built-in WAAS GPS provides precise location
  • 7-hour rechargeable battery means no wires
  • Bluetooth connection to the Garmin Pilot app on iOS or Android
  • Also works with ForeFlight Mobile
  • Connect to Garmin portables: aera 660 and 796/795


Coverage at any altitude

Continuous SiriusXM satellite updates — accessible by ground and air — can help you make better, more timely flight decisions. The SiriusXM network’s powerful satellites deliver seamless coverage across the continental U.S. and its coastal regions as well as southern Canada. Choose from available SiriusXM aviation packages that provide METAR data and animated NEXRAD imagery plus current reports on precipitation, lightning, winds aloft, echo tops, turbulence, freezing levels, TFRs and more. To help you maintain the most current weather picture, the GDL 51 receiver can queue the weather from SiriusXM while your display device is sleeping or turned off so it automatically updates when you turn the screen back on. 


SiriusXM Radio

By simply connecting a compatible Bluetooth headset or audio panel to GDL 51, you can wirelessly listen to your choice of high-quality audio entertainment channels provided by SiriusXM. Volume adjustments and station selection may be accessed through your compatible Garmin aviation portable or mobile device app. If you prefer, a 3.5 mm stereo audio jack positioned on the side of your GDL 51 makes it easy to provide a hardwired audio out connection to an auxiliary device or audio panel in your aircraft. 


Built-in GPS and Attitude Sensors for SVX Display 

In addition to its weather and audio entertainment capabilities, the GDL 51 feature set includes a built-in WAAS GPS receiver. This enables GDL 51 to deliver highly accurate aircraft position, speed and altitude information to your compatible mobile device app. Also, built-in attitude sensors enable select Garmin aviation portables and apps with SVX synthetic vision technology to serve as a backup attitude reference during your flights. With virtual terrain, obstacles, runways, horizon cues, HSI, GPS speed, altitude and more, this brings a whole new perspective to your portable navigation.

You get seamless operation, long range NEXRAD, and subscription fees
We use the GDL51 in an older King Air. I chose it over the ADS-B unit because we make some long flights and wanted the higher resolution NEXRAD for the full US, not just the regional picture.
Paired to the iPad once and it connects immediately every time
Weather data is top-quality and available at all altitudes
More weather products than ADS-B (turbulence, storm cells, icing)
Good battery life
Subscription fees - but I knew this so I really can't complain
Doesn't get NOTAMs (need ADS-B for that)
Our heated windshield blocks the SiriusXM signal

I needed to buy the external antenna and run it to the one point on the windshield that doesn't have embedded wires for heating. Without the antenna, reception was often poor or non-existent. When I used it in my 182, with no external antenna, signal was always excellent.
Fits perfectly and is shaded by the center pillar - seems it could get hot otherwise

Will this work in conjunction with the GDL 39 for traffic?
A shopper on Sep 18, 2017
BEST ANSWER: Please contact garmin aviation support at 1-866-739-5687.
I currently use foreflight with stratus 2s and also a garmin aera 660 with gdl 39, i would like to have the advantages of XM weather, should i get the gdl 51 or SXAR1 to have the whole picture, the idea would be to clean my cockpit from too many devices. any suggestions?

BEST ANSWER: I am a long time user of XM weather, I think I am one of the first 100 original customers. I will not fly without XM. I have been using the SXAR1 with Foreflight since it first became available last December. Now I get all the XM on Foreflight. It is an excellent product, seamlessly integrated. The SXAR1 battery lasts over 8 hours, I cannot tell you how long it will last, as it has never run out on a day of flying. It is a really good solution. I think it is better than the Garmin as it is smaller, and it is cheaper. The Fore Flight XM subscription does not have the Surface Visibility Forecast, Freezing Level, NOTAMS, Special Use Airspace Status and Tropical Storm Tracks with Windfields Observed, nor all the icing information products that I was used to in the Pro subscription plan that I was used to. (NOTAMS, Special Use Airspace Status were never available on XM), and I would really like to see the Freezing level especially, and also the surface visibility forecasts added. I am hoping they will add all those to the XM as it is getting harder an harder to justify XM vs ADS B for many pilots. I fly to Canada regularly so the XM is the only option up there, as ADS B is not available in Canada.
Will Sirius XM weather work in Australia?
A shopper on Jan 26, 2020
BEST ANSWER: No, there is not coverage.
Is a antenna required?
A shopper on Apr 8, 2019
BEST ANSWER: No, the antenna is not required.
For an iPad with an internal GPS running Garmin Pilot, does the GDL-51's WAAS GPS information override the information from the internal iPad GPS? How does this work?
jim K on Mar 10, 2019
BEST ANSWER: Yes, the GDL-51 will override the internal GPS.
Hi, I am interrested in the GPS AHRS functions only, will that work without a suscription?
A shopper on Dec 5, 2017
BEST ANSWER: Yes, without a SiriusXM subscription. You will still need a display to show this information (tablet or GPS).
I own a Garnin 696 with a GMX42 XM antenna mounted and wired in a panel dock. I want the capability of moving the receiver/antenna to another aircraft (for use with an Ipad) without buying another xm subscription. Because the 796 uses the same GMX42 that my 696 uses, will this unit plug and work with my 696? It appears this GDL 51 has an MXC antenna port, does the other end of that antenna cord have a micro USB like the GMX 42?
Isaac D on Oct 14, 2017
BEST ANSWER: As I understand the subscription is tied to the the GXM 42.
Is there a monthly fee?
A shopper on Sep 20, 2017
BEST ANSWER: Yes, there is a monthly fee for the sirus weather.
Can this be used with Foreflight? If not then what apps can it be used with?
A shopper on Aug 13, 2017
BEST ANSWER: It is only available for use with Garmin Pilot.
