Is it possible to take just the electronics panels of a DSP5500 to a dealer for the firmware update? It seems straightforward to remove and unplug the panels, but are there any drawbacks to updating (assuming it is possible) without the drive units.

Trying to avoid shifting 70kg of speaker to the dealer or forking out to cover his expenses in coming to me. Thanks in advance.
