Inputing Signal to "InVision" Headrest monitors/DVD's

[RJD]

Sounds like you have a Revolution II. The major difference between the II and III is:
? TV tuner
? Concealed additional A/V inputs
? Optional: 4 headrest system
? Optional: Wired FM modulator

This is all accomplished through the addition of a small metal box that contains the TV Tuner with the capibility to hard wire the sound through your radio, thus eliminating the need for the wireless FM modulator. This additional box contains the additional RCA jacks for video and audio (one each - so only one auxilliary source), so a "Playstation", etc. can be attached.

The Revolution II is field upgradeable to a Revolution III just by purchasing and installing this additional box. The part number for this box is IN 1460, and it is available through your HUMMER dealer.

Hope this helps, as I have the same unit and it is FANTASTIC!
