VMM418 is Vehicle Memory Module and the version #.
Last chime is the last chime you heard (like when you start the car, it goes thru the instrument cluster check and makes a few chimes). In your case, when you checked, the ABS chime was the last one to chime.
Also, my car was built in August of '05 and the VMM you have is the same I have.
From what I understand, it can not. I may be wrong and get flamed but I don't think so. I know that the 07's got an upgrade on theres and have 0-60 and performance gauge. But you would have to change the dash to change up to theres.
