Yeah, originally, I thought he was going to be the voice of Jazz, since the original voice actor has passed away.
(Plus...come on, Bernie would make an awesome Jazz. "Optimus! I'm 'bout to club Starscream like a baby seal!" One of my favorite episodes of his show...)
Apparently he's the car salesman that sells Bumblebee to Spike.
