I have searched the Internet and have found absolutely no information about whether or not I will lose my rsa/RHVAC module when I install an aftermarket head unit. Any information would be very appreciated.

You will lose those features if you do not use a GMOS-xx(the xx correlates to a number, that depends on what year options your truck has) adapter or equivalent

Go to a website like Sonicelectronics or Crutchfield, they will tell you want you need to install in your car to keep things working correctly.
