Garmin Express doesn't recognize SD card in nuvi 205W

HI,

I am trying to update the map on my nuvi 205W. When I try to update, Garmin Express says "We're unable to install the updates." "The latest software does not fit on your device's internal memory, Please contact Product Support for help with updating your software." The nuvi has an SD card that accommodated the previous map update just fine. I bought a 32 GB microSDHC card that Garmin Express also didn't recognize. I'm using MacOS Sequoia 15.0.1 with Garmin Express 7.23.0.0. Has anyone else had this problem? Thanks.
