Enhance Situational Awareness
GPSMAP 396 comes with a detailed built-in Jeppesen® database along with terrain and U.S. obstacles databases. Using this information, the 396 provides detailed views of your flight route, displayed over realistic topography. For added safety, you can put the unit in Terrain mode for TAWS-like warnings and alerts when proximity conflicts loom ahead.
View Images in Sharp Detail
Viewing the display in any light is easy, thanks to the unit’s 256-color, high-resolution (320 x 480-pixel) sunlight-readable TFT display with adjustable backlighting. The 396 also features USB data transfer, fast processing speed and a rechargeable lithium-ion battery pack.
Add Weather, Radio and Traffic

With a subscription to XM weather and the included GXM 30A smart antenna, you’ll have access to constantly-updated, high-resolution weather data for the U.S., right in the cockpit. Weather information includes Next Generation Radar (NEXRAD), Aviation Routine Weather Reports (METARs), Terminal Aerodrome Forecasts (TAFs), Temporary Flight Restrictions (TFRs), Lightning and Winds Aloft and can be laid directly over the 396’s map. With an additional monthly service fee, GXM 30A delivers XM Satellite Radio to your aircraft. Add a Garmin Mode S transponder, and the 396 can display TIS traffic alerts that identify surrounding air traffic.
