Ditto to Bert. My TV doesn't have audio out so I used my Ipod cable..one endplugged in to the headphone jack on the TV and the other end to the Aux jack on the front of the Jensen (assuming it's a Jensen). Also works on my SOB with a Rockford-Fosgate system, much like a Jensen. Works very well as my TV has crummy speakers..surprise, surprise.
Edit:
Had another thought. If your TV was factory/dealer installed, check to see if it has audio out and there are red and white cables plugged in. If so, you may find TV audio on one of the Aux modes on your system. I found this out by accident on one of my trailers where I found Aux 2 played the TV audio thru the ceiling speakers.
Of course this wasn't pointed out during the PDI.
