How to hook TV into truck's radio

If you truck radio has Bluetooth, you can buy one those Bluetooth transmitter and hook up to your tv headphone jack. I think they sell in truck stop.

 

Do you have a speaker plug on the tv and an aux port on the radio? When I am forced to use a loaner truck while mine is in the shop, I have a small tablet computer I tether to my phone for tv. I use a 3.5 mm patch cord to run from my tablet to my stereo's AUX port. Both have bluetooth, but for some reason there is a 1/2 second delay between what I am seeing and what I am hearing so it looks like a low budget 70's chop-chop movie. The patch cord eliminates that, but it is a wire that you have to keep from getting tripped over.

I did have an old tube type tv years ago that had the same problem you're having, and it didn't have an audio-out plug. I took the tv case apart and snipped the speaker wires, then connected it to an after market plug I got from Radio Shack, then drilled a little hole in the case so I could plug in an external speaker with a long cord, and mounted the speaker near my head. But this was many years ago.

 

If you use a cord try not to let it touch any other cords while plugged into the TV. Mine crossed paths with my cell phone charging cord and the static charge fried the output Jack on the TV.

 

I tried this once and hated it. The sound was coming from the wrong way.
