Maximum Memory Card Size for Garmin Legacy Models

Many Garmin Outdoor models include an expandable memory card slot. The memory card must meet the below requirements to be compatible:

• Card type - microSD card
• Card storage size - up to 4GB (gigabytes)
  
• Card Manufacturer - While any brand of microSD card should work, Garmin has only tested more common brands such as SanDisk or Kingston.

Additional requirements:

• The handheld needs to be at the most recent software version
• Garmin legacy models with expandable memory will only support one downloadable content map per microSD card. Additional downloadable maps will overwrite any maps previously installed.
• Each expandable memory device will be able to recognize up to 2,025 detailed mapping segments
  • Any map segments loaded beyond the 2,025 segment limit, even if there is more room on the microSD card, will not be recognized or displayed by the unit.

The primary purpose of the microSD card is to store detailed mapping such as the street mapping City Navigator NT or the topographical mapping Topo 24K.
