MicroSD Card Size

Does anyone know the largest card size you can put into a Garmin Rino 530HCx?

If you are running the newest firmware, I believe all Garmin units will support as large a card as you like. However, you can only store 4GB of maps. The bigger limitation is that an older design like yours will only support 2025 map segments. You will reach that limit long before you hit 4GB generally. For example, the full US Topo 100k is about 3GB but it contains 6600 segments. So you would max out by loading about 1/3 of the US and would only have about a 1GB file.
