I am moving my CVA-1004 head unit, NVE-N851A nav, CHA-S634 CD changer into my new(est) car. I bought a Pac 7 trigger for video bypass service. After installation, I am unable to access the 'set-up' screen. The disclaimer screen does not clear with pushing 'enter' on remote. I removed the Pac7 bypass and tried to connect the hand brake and foot brake leads on the heat unit and nav unit, but it is not clear in the manuals whether they are looking for 12VDC or ground. I have re-booted the head unit per manual, but no luck. Any advise out there? Much Thanks BB
