I am a first time GPS user and have what I imagine is a newb question. I purchased the Etrx30x which came with the TOPO US 100k on a separate chip. My main intended use is cross country backpacking, so when I got home I purchased the Western 24k topos online.
I tried to download the Western 24k Topos into my device, but there was not enough memory. I had no idea that the device I bought would be unable to handle the maps I intended to use it with. So I swapped a microSD chip from my camcorder into the Etrx30x--it has 30 gigs of capacity. I then was finally able to download my Western 24k topos from the Garmin website to the chip.
The Etrx30x sees the 24k topos from the chip, now, so I know they made it into the device successfully.
But two problems.
1) I also have the TOPO US 100k and would like to have them in the device too, for whenever I am outside the 24k zone. But I cannot figure out a way to load them from their original chip onto the chip I placed in the Etrx30x. I certainly don't want to have to disassemble the device and swap microchips every time I want to move from the 24k to the 100k.
I read that the best tool to manage these kinds of things was Basecamp, so I downloaded and installed it. But I am having real problems understanding how to use it for managing maps.
2) After having installed Basecamp, I plugged my 30x into the computer and stuck the 100k into its card reader. Basecamp sees the 30x and it sees the card. Great! But Basecamp does not seem to be able to see or read the Western 24k maps that are stored on the memory care in the device. I can't work with those maps from Basecamp since I can't seem to get it to see the maps. The chip shows up, but it doesn't show that the maps are on the chip.
This stuff is about as transparent as mud, and is befuddling to a newb. This stuff seems like it should be simple ans straightforward, but I'm not figuring it out. Any help would be appreciated.
