Circuit/System Description
WARNING: This page is about a different car, the 2007 Cadillac XLR. However, it is still accessible from the selected car via links, so may be relevant.
The antenna signal circuit is a coaxial cable that carries the radio signal information received by the antenna. The antenna cable also provides a path for DC current for powering the antenna. The antenna 1 circuit (left) is the green connector at the digital radio receiver (DRR). The antenna 2 circuit (right) is the curry colored connector at the DRR.
