Friend of mine has an 07 base with nav, I have an 07 type s are the hfl modules interchangeable? He is about to trade it in and if they are maybe I could talk him into a swap.

 

There should be no difference between the Type S and non-Type S; they should use the same HFL part number. The only difference in the HFL unit part numbers and prices is due to the bezel color, IIRC.
Confirm that by checking "hands free telephone assembly" on oemacuraparts.com or whichever acura parts site you use.
