What usally follows an Augmented major seventh chord

Question

I don't have a clear understanding of the notation used in the following sentence from the article on Augmented major seventh chord from Wikipedia:

As with dominant seventh chords, non-dominant seventh chords including the augmented major seventh usually progress according to the circle, thus III+_M^7 resolves to vi or VI.

If we are referring to the C maj7(♯5) does the III in III+_M^7 represents C, or does it represent E? , knowing that will allow me to know whether C maj7(♯5) usually resolve to D (when III is C) or F (when III is E)

Answer 1

If your Cmaj7(#5) is interpreted as a III+_M^7, the third degree in A minor, then it should resolve to F which is the sixth degree in A minor.
