Reinstall of Alpine CVA1006 issue

Had this unit installed in owners previous vehicle and all was good, bench tested it prior to reinstall all was good,but now we have the unit fully installed in his new car (04 Sentra Spec V)and we have this little issue. The picture "rolls" not sure how to explain it, but the best I can do is...like on old ass VCRs when the picture would "flip" the tracking would need to be adjusted. Hopefully that makes sense.

Any idea what would cause this to be happening? Like I said, it didn't do this on the bench so thats what has me a little confused. Checked all obvious connections, power, and "din" cable from tuner box to headunit. Hopefully there's a simple remidy for it that somone here can put me on to.

Also on this same unit, is ther any good lubricants that can be used on the gears for the motorized screen?

I would make sure that all the din cables are plugged in securely. As far as lubrication I would think either graphite or white lithium grease.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

I'll double check them, maybe even pull the cable and inspect it...maybe its pinched?
