How do you remove the headrests on an H3?

[jersey]

I purchased the Kenwood DVD/Nav in dash setup, but the dvd doesn't show on screen while driving. It has a 12 foot video out line to connect to rear monitors though and with that in mind I purchased dual headrest dvd monitors. The problem is I can't seem to remove the original front seat headrests. Is there a trick to it?
added info: It's an '06 H3 Cloth headrest.
