Thread: Garmin GB Discoverer v3.00 - National Parks 1:25K and National Trails 1:25K Collection

Anyway, your work is very useful because all three maps can be placed on a 8 Go micro SD, whereas I needed a 16 Go with original National Parks and Trails.

You need more than 16GB, I estimate all maps together are around 20GB!
I also doubt if your GPS will read all 37 img on a 32GB card, my62s has a 16 map limit and the Oregon 600 has a 20 map limit. I have tested these limits with all different map-ID's (the UK maps have only 2 different map-ID's) but I wouldn't be surprised if your GPS doesn't read so many img.
