2023 International HX Navistar Sirius Antenna

Are you able to remove the radio and make sure it hasn't become disconnected from the back of the radio. This is what we see most often as Navistar loves to run a wire 2 feet long between two parts that are 2 feet, 3 inches away from each other.

 

If this is a sleeper unit, I believe it runs down along the dash, to the left side floor boards, and runs along the floor under the skid plate by the door, through to the sleeper cargo bay and then up the left side rear of sleeper and mounts to the roof at the back of the bunk. If the reception was never good, it is also possible it was never plugged in the first place, and the antenna connector is there, just buried a bit in the wiring. It will be near by. You might just have cut some zip ties and search for it. Should be a tan/light brown coloured connector.

 

One of the guys at our company had problems with that on his 22 LT. Dealer ended up just running a new antenna.

 

I know on my HX's all the antennas are mounted to the back of the cab now.
