What exactly is M-Flash, how do I know if the car has it? I pick up my new ride tomorrow.

I know this has probably been a thread a whole bunch, but I searched and couldnt find a good answer.

If you do a search for it, youll find some threads that go into it extensively....

I'm not sure if mine has it either. The next time Im over at the dealers, Im going to have them check for me...
