I have plugged in a micro chip to my Mac but the Mapinstall does not see it. So how do you load .img maps directly to the chip vs using the very slow USB 1 on the etrex? Using the maps from this site.

I have been having issues with the etrex 30 I just got. I would like to load more than one map but I can not figure out how to load more than one map. I assume that because of the file name you have to load what you want all at once? And if you load more maps, you have to reload all of them again?

So I have about 5 maps I would like to load to the etrex but I can't seem to figure out how to check more than one map to load. I use a Mac with Snow Leopard. I have Basecamp, map instal and the manager.

edit: I reread the information for loading maps. So it appears, which I was not doing, that you have to highlight each topo you want and do the send all at the same time. I think I was doing that before, as I could tell from the memory left that it was down low enough that more than one topo was highlighted. I will try again to load just two topos at once. I can see that using a micro chip is much better since for some unknown reason Garmin has used USB 1, which is stupid.

edit 2: Ok, that worked. I was loading each map and then only the first one would show up as I didn't realize you had to load them all at once as they go into the same folder. So each time you want a new topo, you have to reload everything by going to each map you want for that particular download.

I guess you can't see another topo on the GPS unit if you aren't in that area? I can bring up Nevada, I am in Arizona, but I can't view the Nevada topo on the etrex 30.

from this site. I did get Arizona to load and it works fine but going through the same procedure, I can't get Calif. or Nev to load (topos). I don't understand why I could load the Arizona map but not the others.

I use the map install and it takes some time, indicating that the map is being loaded to the etrex but then I can not find the map as it is not listed with the others and again, what is frustrating, is that I use the same procedure that worked fine for the Arizona map.
