If you're looking for silver units - look at marine head units. Functionally they're no different, just saltwater-proofed and much more likely to come in silver. A few of us have Clarion M502s, the head unit itself is nothing special, but matches the dash quite well. Unfortunately it doesn't have a CD player. Kenwood has some nice looking marine head units, and I'm sure others do as well. At a quick glance the Kenwood KMR-555U and Clarion M303 look like possible matches...
