Where should I mount the antenna?

Verify the following:

• For most vehicles, the front, center part of the cab is the best.
• Place the antenna with an unobstructed view of the sky. An obstructed view of the sky may impair system performance. The GPS engine computes a position based on measurements from each satellite to the internal GPS receiver.
• Mount the antenna on, or as close as possible to, the center of your point of measurement. For example, ideal antenna placement on a vehicle is the center of the cab roof, assuming there is a clear view of the sky.
• Position the antenna as high as possible.
