Thanks Men but I want to be able to take the GPS cradle off leaving only the Ram Ball.
I have a Garmin Zumo 660 and anyone who has one knows all the wires are hard wired to the
GPS cradle and when the power cable is attached the cradle can not be removed.
So the plan is to cut the power wire and put in a connection to allow disconnecting.
The Audio out Cable can remain untouched. After much head scratching I have decided to install a cable window in the lid of the left cubby hole thereby allowing me to connect and disconnect
when needed.
