Probably not... they do sell adapters for some though. There is no universal steering wheel control so the aftermarket wouldn't make any money trying to design headunits with that function.
^Just in case you didn't know, the single disc and 6-disc changers are interchangable and the use of steering wheel controls is preserved. I swapped my single for a 6-disc and it works great.
I don't know what the cause of your problem is, but you could always try another unit.
