I basically just solved the problem by buying a Deluxe Radio with an AUX input.
Anyway, I finally got around to fixing my odometer. Hopefully for good this time.
I sourced a donor cluster from a CE2 Mexican Jetta GL and the odometer looked to be in working condition. It went from 241,631 Miles tooooo 160002. To match my car. Here are pics:
And then old vs. new (new is white)
Speedo faceplate on
Andddd in the cluster
