Receiver For Remote Control: Function
WARNING: This page is about a different car, the 2006 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.
The integral antenna receives the transmitted code signal from the remote control. The signal is processed and sent on to TWICE, which is programmed to identify the car's remote controls. If the correct signal is received, the command is carried out.
