hello. i had my unit installed at 6th ave electronics. i have an 02 jetta. i'm thinking of creating a nice custom dash trim. right now i am using a black rubber piece around the z1 that the installer said came with the unit. my question is, did the unit come with another rubber trim piece? maybe a silver one (i could paint it)? i'd like to have a backup and if it was in the box i want to go back to 6th ave to get it back.
