3a. Radio Input Interface (IS32)
The radio input interface is designed to install inline with the radio antenna usually located
on the back of the radio headunit. However, in some cases this radio connection may
be at a remote location in the vehicle. Please consult the vehicle manufacturer’s
information or owner’s manual for more information.
