Prefer the twin centre as the master as it has a mode that the z21 does not. Tried emailing rock but still waiting for a reply. Not best impressed with their support
Has any one slaved their z21 to a twin centre. I have the cable but when trying to use the maintenance manual there is a screen in front of that page (page 29) which reminds me to use the cable. Not able to close that reminder. It is a black z21.
