Hi All, this is my first post here - I’ve recently picked up an Alpine CDA-7846J for my car, and I heard a rattling in the unit and found this (pictured) - does anybody know what this is, and if so, where it needs to go? Hoping to try and get it sorted and in my car in the next week or so - any help is much appreciated!
Picture of it against the unit for scale too.
