PSR 800 fiirmware

I have a Uniden BCD536 and a GRE PSR 800 and have been making backup micro SD cards for both. The Uniden has a firmware folder on the card that contains the latest (or a preferred rollback version) of the firmware. Does the PSR 800 store the firmware on the card or is it applied directly to and is resident in the radio?



May be a few days before I am back on RR so thanks in advance for all replies!
