	• The GPS antenna is in an unsuita-
	ble location.
	• Obstacles are blocking signals
	from the satellites.
	• The position of satellites relative to
	your vehicle is bad.
	• Signals from the GPS satellites
	have been modified to reduce
	accuracy. (GPS satellites are oper-
	ated by the US Department of
	Defense, and the US government
	reserves the right to distort posi-
	tioning data for military reasons.
	This may lead to greater position-
	ing errors.)
	• If a vehicle phone or cellular phone
	is used near the GPS antenna, GPS
	reception may be lost temporarily.
	• Do not cover the GPS antenna with
	spray paint or vehicle wax, because
	this may block the reception of
	GPS signals. Snow buildup can
	also degrade the signals.
