Does look good!

Depending on the age of the HU you might be able to grab the service manual with wiring diagram from the Alpine site. How does the cable from the HU mount into the dock - is it the Apple connector? Is it perhaps the dock that is causing the issue? Long route would be to fabricate your own "dock" hard mounting the Alpine cable.

Edit: Just found this - does it help



for this type of connector
