Fuze+ microsd card not recognized?

I tried the 16GB microSD trick. Didn’t work. Called tech support, spent over an hour with her. She got me through updating the firmware and checking different size microSDs on the Fuze+ and other devices. Bottom line the 16GB doesn’t work in the Fuze (“FORMAT fat32” deal). I have a support number and was told it will be fixed and someone will get back to me within 48 to 72 hours. Stay tuned.
