HRMC-1 and HRMC-5 Huges Remotes - What is the difference?

[Stargazer]

I was trying to sell some HRMC-1 remotes and thought they were HRMC-5 remotes because they look alike and did not know that they had the actual model number on them. What is the difference between the two?

The HRMC-5 has an additional "AUX" button to control other devices the HRMC-1 can't.

I think the HRMC-5 has RF capabilities and the HRMC-1 doesn't.
