FCC  
This device complies with Part 15 of the FCC interference limits for Class B digital devices FOR HOME OR OFFICE USE. These limits  
are designed to provide more reasonable protection against harmful interference in a residential installation and are more stringent  
than “outdoor” requirements. Operation of this device is subject to the following conditions: 1) This device may not cause harmful  
interference and 2) this device must accept any interference received, including interference that may cause undesired operation.

any local traffic regulation or personal judgment and/or knowledge of safe driving practices. Before making any  
maneuvers suggested by the NAV ONE system (for example, a U-turn or a left turn), verify that the maneuver  
can be legally and safely completed. Do not follow route suggestions if they suggest an unsafe or illegal maneuver,  
would place the vehicle in an unsafe situation or would route the vehicle into an area that could be unsafe.  
DO NOT program this NAV ONE while driving. Only a passenger should operate controls or program the unit while  
the vehicle is in motion. The driver should not program the system unless the vehicle is parked in a safe location.  
ONLY glance at the screen when necessary and safe to do so. Listen to the computer voice guidance. If prolonged  
viewing is necessary, pull off the road to a safe location.  
DO NOT use this NAV ONE system to locate emergency services (such as police, fire stations, hospitals and clinics). The  
database may not include all emergency service providers. Use best judgment and ask for directions in these situations.  
DO NOT position the unit in a location that obstructs the driver’s view of the road, instruments or controls to operate the vehicle.  
DO NOT drive the vehicle unless the unit is securely attached to the windshield with the supplied bracket and suction cup or is fastened  
by other reliable means to keep it from becoming a projectile hazard inside the vehicle in the event of a violent maneuver or collision.  
DO NOT mount the unit over airbag panels or within airbag expansion spaces. The force of an expanding airbag  
can thrust objects in its path toward the driver or passengers with injurious result.  
DO position the unit so the screen can be viewed with just a quick glance.  
DO set the volume at a level that will allow the hearing of outside traffic and emergency services.

The Global Positioning System is provided and operated by the U.S. government, which is solely responsible for its accuracy  
and maintenance. The system is subject to changes, which could affect the accuracy and performance of this NAV ONE system.  
This NAV ONE is not waterproof. Do not allow liquids to splash on it nor expose it to rain during operation or  
transfer from vehicle to vehicle.  
Do not disassemble or modify the unit as this may lead to damage. If a problem occurs, stop using the system immediately and  
contact a Cobra dealer. Changes or modifications to the unit may void its compliance with FCC rules and make it illegal to use.

n
The NAV ONE system’s map database provides information on suggested routes without regard to factors that may affect  
the user’s driving experience or the time required to arrive at the desired destination. For example, the system does not  
reflect road detours, closures or construction, some road characteristics (e.g., road surface, slope or grade, weight or  
height restrictions, etc.), temporary traffic congestion, weather conditions and similar factors. Use personal judgment  
or the NAV ONE system’s detour mode to develop an alternate route if necessary.  
n
Do not remove the unit from the windshield or quick release bracket while the unit is turned on. The NAV ONE  
contains a hard drive, which spins at high speed while the unit is turned on. Handling the unit while the drive  
is spinning could damage it. When the unit is off, the hard drive is parked in a more secure condition.  
Dismount the unit when parked. This will not only minimize the chance of theft but will also reduce the  
unit’s exposure to heat and strong sunlight which can shorten the life of the internal components.

Do read the Important safety information sections on pages 4 and 5 of this manual before using this NAV ONE system.

Installation  
Installation  
The unit can be mounted to the vehicle’s windshield with the included bracket and suction cup, or an  
alternative mounting can be devised.  
THE UNIT MUST BE FIRMLY ATTACHED TO THE VEHICLE. If it is not, it can become a projectile  
hazard to vehicle occupants and possibly cause serious injury during a violent maneuver or crash.

the central PRESS button. Be sure the  
button is pressed all the way in to make  
sure ALL the air is out of the suction cup.  
3. Attach the unit to the mounting bracket  
by means of the quick release feature.  
Use the quick release lever to temporarily  
remove the unit from the mounting bracket  
when the vehicle is parked to prevent theft  
or heat damage. Be sure to turn off the power  
before moving the unit to avoid damage to  
the hard drive where the database is stored.  
4. Plug the power cord into the unit and  
the vehicle’s 12 volt power socket.  
2. While maintaining FIRM pressure  
on the button, rotate the lock lever  
over the button.  
The suction cup portion of the bracket  
can be left attached to the windshield  
for quick reinstallation.  
Test suction cup adhesion by pulling on

After installation is complete and the vehicle is in an open area, turn on the unit (press and hold the POWER button on the side of the unit).  
Each time the unit is turned on, a start-up screen appears on the LCD followed by a safety reminder and an opportunity to select a language.

Then, pressing ENTER will bring up either the Main menu or the Continue route guidance menu. Each time the system is turned off  
(press the POWER button again), the system will retain all information to be recalled when it is turned on again.  
When the GPS Navigation System is new (or has been idle for more than seven days or has moved more than 500 miles while off),  
it can take up to five minutes for the system to lock onto the GPS satellites. After such a start-up, the system should be left turned  
on for at least 20 minutes to download GPS satellite data. Having updated satellite data will allow much faster satellite acquisition  
and lock — typically less than a minute — when the unit is turned on again.

Leaving a calculated route  
Within a short distance of the vehicle leaving a calculated route, the NAV ONE system will recognize the deviation and provide helpful  
information. In the case of a missed turn or similar situation, the system will provide voice prompts, such as, “Please make a legal  
U-turn,” to return to the calculated route while the system remains in the active navigation screen.  
If a longer deviation is made and the prompts to return to the route are ignored, the system will calculate a new route to the destination  
— often a mini-route to intercept the original route at a later point — provided the auto reroute option is turned on. The new route will  
be displayed in the active navigation screen and the voice prompts will adjust accordingly. If auto reroute is turned off, the system will  
suspend guidance until the user takes some action such as [Detour] or [Cancel].  
During a trip, the  
NAV ONE system  
offers help if a turn  
is missed or a side  
trip is taken from a  
calculated route. It  
also allows changes  
to be made enroute  
— including detours,  
changing route criteria  
and trip plans, and  
canceling navigation.

GPS system characteristics/operation and NAV ONE system specifications  
The Global Positioning System (GPS) is a space-based radionavigation system. It consists of 24 satellites (which orbit the Earth at  
an altitude of approximately 11,000 miles) and ground stations. GPS provides users with accurate information on position, velocity  
. . . . . . . Ü  
GPS basics  
and time. This is available anywhere in the world and in most weather conditions. GPS was initiated by The United States Department  
of Defense in 1973 to reduce the proliferation of navigation aids. By creating a robust system that overcame the limitations of many  
previously existing navigation systems, GPS became attractive to a broader spectrum of users. GPS has been successful in classic  
applications such as aviation and marine navigation since it was first developed. Since then, it has become useful for a wide range  
of people because its capabilities are accessible using small, affordable equipment.  
. . . . . . . . . Ü  
How GPS  
works  
The GPS satellite network transmits radio signals to earth from high earth orbit. GPS service provides users with extremely  
accurate positioning information anywhere on or near the surface of the earth. To accomplish this, each of the 24 satellites emits  
signals to receivers below. GPS determines location by computing the difference between the time that a signal is sent and the time  
it is received. GPS satellites carry atomic clocks that provide extremely accurate time information. The time information is placed  
in the codes broadcast by the satellite so that a receiver can continuously determine the time the signal was broadcast. The signal  
contains data that the NAV ONE system uses to compute the locations of the satellites and to make other adjustments needed for  
accurate positioning. The NAV ONE system uses the time difference between the time of signal reception and the broadcast time  
to compute the distance from the receiver to the satellite. With information about the distance to four satellites and the location  
of each satellite when the signal was sent, the NAV ONE system can compute its own position: latitude and longitude.
