For those of you who either have a Defective HU or simply want to upgrade to add features; the latter 2 of the New Part numbers (listed above) contain integrated USB and BT options. All that is required is to add the cabling and some coding to the HU (it comes pre-coded, but not to the car so voice command will be in German or something).
What you will need:
HU with embedded BT & USB (also includes Sirius and HD Radio
MOST bus HU with BT/USB/Sirius/HD Radio
or
NON MOST bus HU with BT/USB/Sirius/HD Radio
Note these are US part numbers, there are comparable part numbers in EU which have DAB and do not have Sirius.
And:
DELETED - A 2 conductor, shielded wirewhich can be sourced at radio shack like places (not necessary with retrofit harness).

FIXED! - found that there is a retrofit mic wiring harness so you don't have to build one!
