Ford EDGE Owner's Manual page 340

• An authorized dealer needs to install mobile communications systems.
Improper installation may harm the operation of your vehicle,
particularly if the manufacturer did not design the mobile
communication system specifically for automotive use.
• If you or an authorized Ford dealer add any non-Ford custom
electrical or electronic accessories or components to your vehicle, you
may adversely affect battery performance and durability. In addition,
you may also adversely affect the performance of other electrical
systems in the vehicle.
