On the cpu issue I can only assume that the new model radio has been built to match the Panasonic radio. I have submitted a FOIA request with FCC to get the schematics. ( might work might not). Got the handle bar switches from a MC junk yard. 60$ No splitter on the radio pointed the FM antenna down between the saddlebag and fender. Adapted the OEM mount to accept CB antenna. PB mounted in one of the blank holes could not find a actuator to wire back in the switch on the FM controles. Other than the PB i think it looks factory.
