You must go into the SWDL (Software Download) Developer Menu and select User-Defined mode . Uncheck the AMP/Bose/B&O categories. Flashing the main unit software over the amplifier's parameters will corrupt the sound module's parameterizations, resulting in absolute silence and a trip to a component protection dealer.
