HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Did you check the fuses with a voltmeter or just visually? Do you have a voltmeter for testing and good understanding of automotive electrical and computer systems?

I will need the vin number to pull the schematics for the MMI to see what may have been fried by the reverse polarization.
