I am having the often reported problem of trying to load two maps on a Garmin. (Ortopo and TopoIdaho both from this site). When I load one, I appear to overwrite the other. I am dealing with an Astro 320 which is a new unit released this summer, so I believe it probably has the most current software. I am using Basecamp on a 32bit PC. I have reviewed the forum discussions and I would like to deal with the problem so I can use either map on the GPS without opening both.
As I understand it, I need to change the file name on at least one map from gmapsup.img to something else (such as oretopo.img. I believe it is the file name on the 320, and not the name of the file on my computer that I need to change(?) How do I find the file name on the gps unit? Look somewhere using Basecamp while the unit is connected to the PC? I have tried the various possiblities I can see and cannot seem to get to it. (If it is the name of the file stored in my computer how do I find it there?) The install wizard does not seem to give me a choice to change the name before I install a map and I cannot find the img file name on the GPS unit or a way to change it if I did.
