I can't figure out how to update firmware to the most recent version and I can't figure out which version is the most recent. From the website it looks like it's 1.5 or later. Can someone help give me info on how to bring everything up to date please? I know it's been discontinued, but would be good to have the latest functioning software! Also, someone mentioned that a bad SD card could keep it from updating? (if I read that correctly) I didn't even know there was an SD card in the MCR. If so, where it is exactly? Thanks and hope I can get answers to these questions. Much appreciated! Greg K.
