What is the function of the black box on the right side of the rearview mirror? My car does not have onstar, do I need it?

This box is for the rain sensitive wipers.
Rainsense Wipers (If Equipped) The moisture sensor is mounted on the passenger’s interior side of the windshield behind the rearview mirror and is used to automatically operate the wipers by monitoring the amount of moisture that is on the windshield. The Rainsense system can be activated by moving the wiper lever to INT. Set the wiper control band to one of the five sensitivity settings within the delay area. The bottom INT ADJ position is the lowest sensitivity setting. This allows more water to collect on the windshield between wipes. You can increase the sensitivity of the system and the frequency of wipes by turning the INT ADJ band up towards the wider lines. A single wipe will occur each time you turn the wiper control band to a higher sensitivity setting. The Rainsense wipers operate in a delay mode as well as a continuous low or high speed depending on the amount of moisture on the windshield and the sensitivity setting. The MIST and “wash” cycles operate as normal and are not affected by the Rainsense function. NOTICE: The wipers must be turned off when going through a car wash to avoid damage. It is important to note that the Rainsense delay wiping feature can be overridden at any time by manually changing the wiper control to LO or HI speed. NOTICE: Do not place stickers or other items on the exterior glass surface directly in front of the rainsensor. Doing this could cause the rainsensor to malfunction.

What he said. On the earlier non-OnStar cars, it was located next to the mirror housing. On the OnStar cars, it was incorporated into the housing.
