I have a navnet mfdbb mPu-001. It's going into installation wizard and nothing, control pad isn't doing anything, haven't tried sync yet. If sync fails, then go to wired keyboard?if that fails Master shutdown, power and cancel on the keypad or is that only mfd12? Say all else fails can I take an mfd12 and use it in place of my mfdbb, is there a control module for mfd12 or its in the screen? Will it communicate with other furuno devices
