I was thinking of doing this too... But question... What does the "A" Stand for in the 6.62a? I currently have the old 6.11c and i'm assuming the "C" stands for "Civic" while the "A" could be for the "Accord"? Could there be differences between the Nav DVD's from other Honda models? Can the 6.62 of an Accord, Odyssey, Pilot, etc be any different of 6.62 of a Civic?
