    Q:
    How to replace the cellular communications/digital radio antenna on GMC Envoy? Posted by Customer
    A:
    Start by lowering the front area of the headliner before replacing the Cellular Communications/Digital Radio Antenna. Disconnect power connections from digital radio antenna assembly before removing its retaining bolt and retainer from the antenna. A gentle squeeze of the plastic retainer frees the antenna assembly from the roof panel while upward motion allows you to remove it from the roof. You should place the antenna assembly on top of the roof with the proper indexing of the anti-rotation pin during your roof panel descent. Accomplish installation by adding the retainer along with its bolt while securing the bolt at 6 Nm (53 lb in) before joining the antenna electrical connectors. Finally, reinstall the headliner.
