may cause static interference in the
radio. Unplug the mobile device or
turn it off if this happens.
Fixed Mast Antenna
The fixed mast antenna will go
through most car washes as long as
it is securely attached. If the
antenna becomes slightly bent,
straighten it out by hand. If it is
badly bent, replace it.
Occasionally check that the antenna
is tight at the base. If tightening is
required, protect the paint from
damage.
Multi-Band Antenna
The roof antenna is for OnStar,
SXM, and GPS (Global Positioning
System). Keep clear of obstructions
for clear reception. If the vehicle has
a sunroof, and it is open, reception
can also be affected.
