You wont be able to get one, you would have to extend it yourself, also if you DONT have touch and connect stereo, the screen will display no info except date and time anyway

The horn is under the battery tray and has its own battery connected to it. Good luck finding a replacement one, like everything with the antara, all the parts are like trying to find rocking horse poo. I wuld try disconnecting the tilt sensor under the passenger seat first and see if that fixes it, as passing cars ,trucks etc can set off the alarm by rocking the car and the tilt sensor if faulty will think its being moved.
