What is the largest size memory card supported by my outdoor mass storage or MTP device?

09/28/2015

Many Garmin outdoor mass storage devices include an expandable memory slot. A memory card can be inserted into this slot and used to store the following:

Additional mapping
BirdsEye imagery
Photos (on devices with camera)
GPX files including geocaches, waypoints, routes and tracks
When selecting a memory card, be mindful of the device requirements:

Card form factor (the shape of the card):
microSD card - Most Garmin mass storage devices utilize this form factor
SD Card - Colorado Series*
Card Speed Class (the speed information can be read from or written to the card):
Standard speed class - Most Garmin mass storage devices can use any card with a rating of Class 4 through Class 10
Class 10 and UHS speed class - VIRB, VIRB Elite, VIRB X/XE may experience stutter, pixelation or lag in the video quality when using a card rated below Class 10
Card Size (the amount of storage space on the card):
128 gigabytes (GB) - VIRB X and VIRB XE
64 gigabytes (GB) - VIRB, VIRB Elite and Monterra (card must be formatted to FAT 32 when using with Monterra)
32 gigabytes (GB) - Most Garmin mass storage devices can use cards up to this size
Smaller Cards - Devices will detected cards with as little as 64 megabytes (MB), but few maps will completely load to a card that is this small: Check mapping requirements prior to purchasing a microSD card
Manufacturer (Brand of Card):
While any brand of microSD card should work, Garmin has only tested more common brands such as SanDisk or Kingston.
In addition to the above memory card limitations, there may be other file limitations that apply to your device; for more information reference the FAQ, "What are the file limitations of my outdoor mass storage device?"

* A microSD card can be used with a SD card adapter
