Montana 750i SD Card - 32GB Max... Really?

A month ago, I bought Garmin's premier InReach product.  Today, I found out that the latest maps won't fit on the device and it is limited to a 32GB SD card. (according to Garmin Tech Support)... 

I heard of planned obsolescence, but this is ridiculous.  Come on Garmin... get with the times.

I have a 64GB card in my cell phone that I am replacing with a 512GB card.  I planned on using the 64GB card in the 750i.  Has anyone tried a larger SD card in a 750i?

Thanks
