GPS
RECEPTION
IMPROVE YOUR SIGNAL
1. Activate your KP2 in an area
without large buildings.
2. The optimum operating
temperature for your vehicle’s
GPS is -10°C~50°C
3. When first using your KP2 or
turning it on after a period
(>3 days), allow more time to
recognize your current location.
RECEPTION MAY BE IMPAIRED:
1. If there is an object at the end of the GPS antenna
2. If your vehicle has metallic elements on the windshields
3. If you install equipment generating electromagnetic waves that
interfere with the GPS signal in the vehicle (Ex: Other GPS devices
like certain wireless activated alarms, MP3 and CD players and
camera alarms use GPS.)
4. If you use a receiver connected by cable. You can avoid electric
interference by changing the receiver’s location (antenna).
5. On heavily overcast or cloudy days if the vehicle is:
• In a covered place such as under a bridge or raised roadway
• In a tunnel
• In an underground roadway or a parking area
• Inside a building or garage

current position when the vehicle is moving than when it’s stationary.
