C70 convertible CD changer location?

[Fred Dehl]

Where is the 6CD changer installed in the C70 convertible? I have the
surround system with the SC-901 head unit, and it has the changer
controller cable, but I don't see where the changer would be installed.
I've removed all the trunk liners and don't see the other end of the
controller cable...

thanks.
