Don't know if this helps, but retrofitmybimmer.com sells EVO head units, and if that would allow updating the TCM (telematics module) to a matching unit, it could be a possible fix. As I have read here, just updating the TCM won't work with the NEXT head unit in my 5/15 M3. The aforementioned head unit is currently priced at $1400 though.
