To listen to sat radio while driving..... Use the home theater system in the compartment to the right
Way better sound, Way way better sound.
If you do not have one then if you have a LINE IN on the daah radio you can use it (just feed the Red and White lines down the A pillar)
Or you can re-transmit (Same leads to an I-Beam or simular fm adapter)
Or you can add an AUX IN to the Dash radio.
Or you can add a small stereo (Shelf type) from Best buy and feed it.
Lots of options which do not involve the TV and most all of them give better sound.
Home is where I park it!
