There are 2 types of Jensen radios that can go in the TC. One with CD player and the other has a aux input on the front. I have the one with Aux input so I can plug in an MP3 player. I have the Jensen JHD1510 model. It also has a plug in in the back to accept Sirius satellite and an Ipod into the back of the radio. The radio can then control the Sirius or Ipod by the front knobs. The Ipod when plugged in the back 8-pin plug will continiously charge the Ipod when the ignition is on. The radio comes with 2 thin metal slides (called a removal key) that can be inserted along the sides of the radio and allows it to snap out of or slide into the mounting bracket under the headliner. The 2, 4" speakers are mounted in the back part of the head liner and face forward, slightly angled to the passenger and driver. The installer at the dealer removed the entire head liner from the TC, and attached the rear speakers through the back of the head liner. When the headliner was off, he mounted to rubber, flexible antenna in the back and center part of the cab. Then he reinstalled the headliner, pulled the connections/wires through the radio opening and attached them to the radio. The radio then slides into the mounting bracket and snaps in place. I am sure other radios would work but they may require a little more work than this setup.
