I recently purchased a new Alpine CDE-172BT Bluetooth Receiver. I currently have an old Alpine headunit 7897 which had the AI-Net cd changer controls, installed in my car. I think I installed this around 2006 in a 2006 honda accord coupe lx, where I disconnected the factor radio. I am wondering if I would be able to just pop out the old unit and plug in a new one or am I going to need to change the wiring harness now that this new radio has items such as bluetooth and usb, which my current radio did not have.
