Garmin GDL 40 Weather Receiver
On-Demand Cellular Marine Weather Receiver for Canada maple leaf

Discontinued. No longer available.

A low-cost, on-demand weather solution for nearshore and inland boaters, the GDL 40 combines NMEA 2000® compatibility with reliable cellular network delivery.

Get Reliable, Real-Time Weather

The GDL 40 provides a number of weather features previously only available over satellite networks. Simply plug the system into any compatible Garmin chartplotter display and begin accessing on-demand radar, wind speed/direction, surface temperature, warnings, forecasts and much more. Because the system requires you to be within range of a cellular tower, it’s an ideal solution for boaters that remain near shore.

The GDL 40 is NMEA 2000 compatible for easy plug-and-play installation. In addition to conventional pole or flush surface mounting, the GDL 40 can also be attached to the underside of many fiberglass or wooden decks, making it easily concealable. For improved reception, a third-party external antenna can be attached.

Pay As You Go

Because the GDL 40 receives data via cellular networks rather than satellites, it can provide weather information at a fraction of the cost. The system employs an on-demand cost structure, so there are no monthly subscription fees, only a small annual activation fee – the first of which is included in the price of the device.

Once you’ve activated your GDL 40 online at, you can then purchase day passes from the device for just $6.99 and roaming passes for $9.99 per day. A day pass provides you with 24 hours of continuous weather data. After each year of service, the GDL 40 requires an annual fee of $9.99 in order to continue connecting to the cellular data networks. Once you have renewed your annual subscription, you can then continue purchasing day passes as desired.
