2 Basic Operation
2.1 Power On/Off Charging
Use only the power cords that are supplied with the
GPS to charge your system. Use of other cords is not
recommended and can void your warranty as they
may look the same as the provided cords but may
not provide sufficient power to fully charge the GPS.
Plug in the GPS power cord into the slot marked
USB. Use the power button found at the top of the
GPS to turn ON and OFF the device. Do not attempt
to charge the GPS by plugging it into a computer as
the charge will not be sufficient. It is recommended
to completely power down the GPS each night after
using. Hold the power button down a few seconds
until you see "Sleep" and "Shut", select "Shut" as it is
an abbreviation for "Shut Down". The "Sleep"
function can be used if you are simply stopping to
fuel the vehicle and plan to resume your trip within
an hour or two.

15
Basic Operation
TIP - Turn on the vehicle then attach the power cord
to the GPS to avoid the possibility of a damaging
electrical surge. Avoid the use of an inverter until you
are sure you have the correct power. Refrain from
sharing the GPS with the same power outlet as other
devices as the GPS requires more power than the
external accessories support. The two to three plug Y
adapters distribute power among the devices and will
therefore most likely leave an insufficient amount of
power for the GPS.
Truck and coach drivers should always use the
provided vehicle power cord to power the GPS while
in use in the vehicle. Power the GPS using either the
DC (vehicle charger), the AC (wall charger), or the
built-in battery. Please keep in mind that the built in
battery is strictly for back up use and should not be
relied upon for commercial drivers.
NOTE - USB computer cables do not provide sufficient
power to charge the GPS. Use the provided wall
charger or the vehicle charger instead.
Hardware User Guide
16
The GPS features a built-in Li-On battery to supply
power when it is not connected to a power source.
The battery indicator will show bars flashing as it is
charging. When fully charged, the LED will change
from red to blue. The battery icon will not
change colors.
Depending on the Backlight brightness level, and
other functions such as Bluetooth and FM
connection, you can expect approximately 45-90
minutes of use without a charger. It is
recommended to always drive with the vehicle
charger cord plugged into the GPS. Be sure to take
proper precautions to protect the GPS. Do not leave
near a fire, do not allow it to get wet, do not
attempt to open the GPS.
2.2 Window Mount
Assemble the plastic cradle to the window mount.
Attach the GPS to the included window mount and
position in a location where it has an unobstructed
view of the sky so it receives a strong satellite signal.
2.3 Audio Out
Attach an external speaker or headphones as
desired.

17
Basic Operation
2.4 Stylus
Use of the stylus is generally not necessary.
However, in the case that you need to reset or
recalibrate the GPS you will want to use the stylus.
The stylus can be found in a slot on the back on the
bottom left of the GPS. Be sure to replace the stylus
in the slot for future use. Do not attempt to use a
sharp object such as a pen or pencil as it will damage
the screen.
2.5 Micro SD Slot
The memory card slot is intentionally left empty. You
can use any micro SD card for music, video, and
picture use on the GPS. Program and map updates
are released on micro SD cards which have a self
installer. Contact TeleType for details regarding the
purchase of an update plan.
2.6 USB Port
Use the USB port to power the GPS using one of the
power cords provided with your GPS. (See the
section above about Power). The purpose of
connecting the GPS to a computer is only to copy
your entertainment files such as music, video, and
photos to a memory card. You can alternatively copy
directly to a memory card without connecting the
GPS to the computer. Updates are done via SD card
so please do not attempt to update the GPS by
Hardware User Guide
18
connecting it to a computer.
2.7 Reset
After installing an update, or if the device seems to
be permanently frozen on a particular screen, you
may need to reset the GPS. Insert the stylus (or
gently use a paper clip) into the tiny hole which
appears to have a golden plate on the back of the
GPS. The hole is unmarked (refer to the photo above
marked with letter "F").
2.8 AV-IN
Attach a rearview camera using a 2.5mm set of RCA
cables. (Camera and cables sold separately). Once
you attach the camera it will appear automatically
on the screen. Contact TeleType for assistance with
wiring.

3 Main Menu
The primary purpose of this GPS is to provide
navigation for commercial drivers. In most cases you
will not need to use the Main Menu functions very
often. Usually you will simply tap "Navigation" to
launch the navigation software. Swipe the screen up

Main Menu
3.1 Navigation
The WorldNav 7650 Truck GPS features truck
specific routing keeping you away from low bridges,
commercially restricted areas, and more .
Keep in mind that many factors such as high, dense
buildings (in the tunnel, between the high building,
underground parking, under the trestle), various
weather condition, and closure of the satellite will
affect the ability to receive signal so as to result in
inaccurate position, inefficiency of navigation
operation and system function. To learn more about
the navigation software please refer to the
WorldNav GPS Software guide.
3.2 Bluetooth
This GPS device has the ability to connect with a
supported Bluetooth-enabled cell phone, allowing
you to make and receive calls directly from your
GPS. Most of the functions on the Bluetooth menu
have now been replaced by your phone functions,
therefore you will just need to pair the GPS to your
phone. The other functions on the Bluetooth menu
are no longer needed and will be disregarded in this
guide. Instructions for pairing the GPS with your
phone are given below.
Hardware User Guide
22
TIP - If you have trouble connecting to your phone you
might want to have your phone search for the GPS.
The Bluetooth passcode for the GPS is 1234.
1. Begin by enabling the Bluetooth setting on your
cell phone. Be sure your phone is in "discoverable"
mode before proceeding.
2. Tap the Bluetooth icon on the GPS Main Menu
screen. The red X will change to a green check mark
when Bluetooth has been successfully turned on.
You will need only the buttons outlined above. Notice that
Bluetooth has been turned on.
3. Tap the Pair/Connect icon

23
Main Menu
Once you have connected the GPS to your phone it will
remember the name. Press Connect to re-connect to that phone.
At some point in the process your phone will require
you to enter the GPS passcode in order to proceed.
At that point you need to enter the number: 1234.
(You can change that number later by using the
"Modify the PIN" button on the GPS).
Check the box marked Auto-Connect to
automatically pair the GPS to this phone each time
you start the GPS.
Check the box marked "Auto-answer" if you want
the GPS to automatically pick up the call even while
you are driving.
4. To exit the menu press the circular arrow
found in the top right of the menu.
Hardware User Guide

Main Menu
3.4 Tools
GPS Information
The GPS Information menu lets you test the GPS
device without using the WorldNav navigation
software. You need at least 4 satellites to lock into
position with accuracy. The blue bars will turn green
as the GPS obtains proper positioning information. If
this menu shows that you are not able to lock into
position, you can press the "Reset" (on the bottom
left of the menu). The system will try again from the
beginning to lock into position.
GPS Information
Unit Conversion

distances, weights, and more, from pounds to
kilometers for example.
Hardware User Guide
26
Calculator
For your convenience, a calculator function is
included.
Screen Calibration
Occasionally you may need to recalibrate the touch
screen if you notice that incorrect letters or
functions are appearing. Press the Calibration icon.
Use the stylus provided with the GPS (or any other
stylus) to accomplish the task. Use the stylus to
press on the target which looks like a plus sign [+].
The target will move around the screen. Continue
this process as it moves to the left, right, upper, and
lower parts of the screen. You may need to repeat
the entire process once or twice if the screen is
more severely out of alignment. Tap <OK> when
complete.
Calibration Screen

27
Main Menu
Press the target and follow it around the screen to calibrate.
3.5 FM Transmitter
The FM feature enables you to link your device
to an unused radio frequency channel, thereby
allowing you to hear your route instructions over
the radio speakers which means you can turn the
volume up very high on the radio in case your truck
is noisy. Select a frequency from the FM menu and
then set your radio dial to that frequency.
Set the desired FM frequency on the GPS. Set the
same frequency on the FM radio of your vehicle.
Example: Set the GPS to 76.0 and the vehicle radio
to 76.0. The function is intended for use while you
are not playing music. However, in some cases
depending upon the strength of the FM signal the
GPS instructions will play over a muted sound of the
music. Be sure to keep the GPS powered with the
proper cord as the FM function will not work when
strictly on battery power.
Hardware User Guide
28
Turn On FM to hear voice instructions through your FM Radio.
FM transmitter is to transmit the audio signal into
receiving device, Take FM 90.0mhz for example, now
the navigation frequency is same as receiving
frequency, is 90.0MHZ, now the two devices are in
same frequency band, which make the navigation
can output the sound.
NOTE - When FM is turned on you will not hear any
sound from the GPS. Be sure to turn off the FM option if
you want to resume hearing sound directly from the
GPS.

29
Main Menu
3.6 System
Volume
The GPS is set to the loudest volume setting for the
speaker. If you prefer not to hear the taps on the
screen you can tap the arrows to change the setting
to be turned off or made lower.
Factory Defaults are set to the loudest settings.
Hardware User Guide
30
Backlight
It is recommended to always keep the GPS powered
by a charging cord, this will allow you to keep the
backlight setting to "Always ON", and keep the
brightest setting during the day, without worrying
about the battery drain. The WorldNav navigation
software can automatically dim the screen for night
driving. If however you would like to manually adjust
the brightness, use the backlight function.
Adjust the brightness to your liking and keep "Always ON".
Date and Time
Changing the date and time on the device will have
no effect on the information you see in the
navigation portion of the device as that information
is automatically taken from the GPS satellites after
you lock into position.

31
Main Menu
Language
Select language to set system language. Note that
the language choice here does not apply to the
navigation software.
System Information
In general you will not need to access this menu as it
relates strictly to the hardware, none of the
information relates to the navigation software.
Navi Path
It is recommended to leave the Auto run GPS setting
on the default position of OFF. If however you would
rather not have to press "Navigation" each time you
want to use the GPS you can move the slider bar to
the left. This means that each time you turn on the
GPS it will automatically go into Navigation mode.
Be careful, if you do this then it will be more difficult
to access the other menus of the GPS such as
Calibration, Backlight, FM, Bluetooth, etc.
Hardware User Guide
32
The bottom portion of this menu stores the location
of the WorldNav navigation software so that when
you push "Navigation" on your GPS it knows where
to find the software. Do not change this setting
unless specifically instructed by a TeleType support
technician. If you change this by mistake you will not
be able to use the navigation function.
It is best not to change anything in the Navigation Path Setting
3.7 AV-in
Attach a rearview camera using a 2.5mm cable.
(Camera and cables sold separately). Once you
attach the camera it will appear automatically on
the screen. Contact TeleType for assistance with
