Garmin ActiveCaptain SD Card/Class Recommendation

The ActiveCaptain™ App utilizes a micro/SD for most compatible Garmin devices¹ in order to transfer data such as chart and software updates to the chartplotter.

SD Card Recommendation

• Speed: Ultra High Speed Class 3 (U3) or Class 1 (U1), or Class 10 (C10)
  Class 2,4, and 6 micro/SD cards will work, however, the lower write speed may result in a longer transfer process
  
  
• Capacity: Up to 1TB*
  As of January 2024, newer Garmin devices can utilize up to this posted limit*. Cards less than 8GB will not have enough capacity to store both software and chart downloads 
  
  
• Physical Size: SD or MicroSD
  Refer to the Garmin device owners manual for the required size
  
  
• Manufacturer: Name brands such as Kingston, SanDisk, PNY, or Transcend are recommended
  Due to the rise of counterfeit SD cards, they should be purchased from legitimate retailers
  
  

¹The Striker Plus 7/9 do not utilize a micro/SD card

* Not all devices are capable of using the 1TB Sd cards. Refer to New exFAT support on Garmin Marine Devices. for a devices that can use the exFAT file system.
