Deane,
All the units shipped out from Roland had Version 1.04. If you go to www.rolandus.com website you can go to products, keyboards, arranger, BK7, downloads and there you will find version 1.05 with easy directions and upgrade the BK7m. As upgrades come out this is where you will go to find the latest. It takes about 30 seconds to upgrade the module using a USB thumb drive.
