For those of you who have rugrats in the backseat and need something to occupy their minds in order to quiet their mouths, here’s some good news. Sirius’ Backseat TV system has now started shipping from select Sirius retailers. It’s compatible with most of the aftermarket or factory-installed video monitors, and has an integrated FM transmitter/AUX output to provide audio.

With multi-zone operation available, you can now entertain your kids with some cartoons, giving your aching ears a break while you enjoy some music up front with Sirius Satellite Radio. The Sirius Backseat TV SCV1 will cost you $299.99.

Polk Audio has apparently begun shipments of a Sirius tuner component product it first announced late last year. The Polk Audio SR-H1000 is now available for around $350.
