I had the Topo 24k Northeast installed on my 700. At the time I didn't have an SD card installed. After seeing how much memory the maps consumed and how little the device has (really Garmin? You should be embarrassed that there's less than 5 GB usable with the base maps installed) I installed a 32 GB SD card. With the card in I removed the 24k map from the device, then reinstalled it through Garmin Express to the SD card. Since then I cannot use the map in Basecamp. I've tried everything I can think of, but when I select that particular map I get "A error occurred when attempting to use the TOPO U.S. 24K Northeast v3 Map Product."
I also have the north central and southwest 24k maps installed to the SD card and they work fine.
