Duplicate Maps Detected (downloaded TOPO map)

Former Member over 7 years ago

I am using a Garmin GPSMAP 64s handheld unit along with BaseCamp version 4.6.2. I have downloaded three different topo maps from Garmin. The TOPO U.S. 24K Northeast v3 map and the TOPO U.S. 24K Southeast v3 map both work fine.

The TOPO U.S. 24K North Central v3 map, however, appears twice in the Maps menu up top. It says "TOPO U.S. 24K North Central v3 (Memory Card)". Why does it appear 2x, and why does it have "Memory Card" next to each of them? The Northeast and Southeast maps don't have this. Also, it is listed twice in my User Data folder.

When I choose one of them it says, "Duplicate Maps Detected. The map TOPO U.S. 24K North Central v3 is also installed on this computer. Certain operations will perform much faster with the installed map. Would you like to use the installed version instead?

I've installed two pictures to show what is going on.

How come this is happening with just the one map? Thanks.

Well perhaps they are on a memory card while the others are installed to your PC?

Run JaVaWa's GMTK program as that will identify exactly what you have loaded on your PC http://www.javawa.nl/gmtk_en.html

Then run Device Manager to establish what's on your device and its sd card http://www.javawa.nl/jdm_en.html

Thanks for helping. I installed both pieces of software - check the two screen shots. On my PC (I didn't take a snapshot of it) I only have two Iceland maps. They're working fine. Now on my Garmin handheld SD card you'll see all of the TOPO maps that I downloaded from Garmin. It looks like there is an East and West version of TOPO U.S. 24K North Central v3. I guess they had to split them up for some reason.

I still don't understand why it says "(Memory Card)" next to the name like I outlined in my initial post.
I also don't understand why it's saying that the map is also installed on my computer when it's not. Hmm....ciq.forums.garmin.com/.../1233140.png

OK I used the Device Manager to change the names of both of the two TOPO U.S. 24K North Central v3 maps "in BaseCamp" and it fixed my issue. Thanks a lot!
