1.1) Installation Hints

 Make sure to clean the windshield and suction cup before installation. Use glass cleaner or

rubbing alcohol.

 To attach the bracket to the windshield:

1. Make sure the locking lever is in the UP position

2. Lightly moisten the suction cup

3. Firmly hold the suction cup against the windshield

4. Push the locking lever.

 The 7750 PLT comes with a rubber bumper to protect your dash. If you let the unit rest on

the dash, stick the rubber bumper onto the bottom of your unit.

 The GPS antenna is located at the top of the unit. During installation, arrange the mounting

bracket so that it does not block the top of your unit.

Using the Mounting Disc

Note: The adhesive pad is a separate piece. The pad must first be stuck to the disk.

1. Find a flat part of the dash to attach the mounting disc.

2. Clean the dash with the enclosed alcohol pad.

3. Clean the DULL side of the mounting disk with the alcohol pad (not the shiny side).

4. Peel the backing from one side of the adhesive pad and then press the pad onto the DULL side of the mounting plate.

5. Peel the other backing from the adhesive pad and then press the mounting plate into position on the dash.

6. Clean both the mounting plate and the suction cup with the alcohol pad.

7. The mounting bracket (suction cup) can now be attached to the mounting plate.

Once the plate is installed, it CANNOT be reused!

NOTE:

To create a secure mount, the plate uses a strong adhesive. Please note that should you ever want to remove the plate, it might leave a mark on your dash. So please decide in advance whether you really want to use it.

2.1) Setting up a truck

1. Tap anywhere on the map screen.

2. Tap on SETTINGS (at the top).

4.9) Stopping a trip

To cancel a route:

STEP 1 – Tap on the “star” icon in the lower-right

STEP 2 – Tap on “Stop”

4.10) Adding an intermediate destination

Maybe you need to pick up a load before traveling to a final destination. You can program the pickup point as an intermediate stop.

Or maybe you are traveling to your home terminal, but you want to stop off at Joe’s Smokey Links for some of your favorite sausages.

1. Enter the final destination and then tap on ROUTE OPTION.

2. Tap on VIA LOCATION.

3. Enter the intermediate destination.

4. Calculate the route.

The nav unit will first bring you to the intermediate destination, and then automatically direct you to the final destination.

You can add only one intermediate destination. If you need to add more than one, then choose Multi-Route instead.

4.11) Creating a Multi-Route

Multi-Route lets you make one long route that consists of multiple destinations. For example you can create a Multi-Route that takes you to a pick-up, makes an intermediate stop (truckstop, etc.) and then to a drop-off. Or you could program an entire day of activity that consists of multiple pick-ups and drop-offs. There is no limit to how many destinations you program.

1. Tap anywhere on the map screen.

2. Tap on Tools at the top.

3. Tap on Multi Route.

4. Tap on Create Multi-Route 5. Tap on ADD

6. Now you can choose a destination by any of the listed methods:

7.2) How to check the map version and update the maps

To check the map version:

1. Tap anywhere on the map screen.

2. Tap on SETTINGS (at the top).

3. Tap on DEVICE.

4. Scroll down until you see VERSION. Tap on VERSION.

The map version should now visible:

The mapping database is much too large to download from the internet. Map updates are supplied on a DVD.

To order a map update, please call Cobra Customer Service at 773-889-3087.

8.1) It says “Some of the roads on this route are not on the National Network”

What this means is that part of the route is on secondary (local) roads. This is common when making pickups and deliveries.

For information about the National Network, please click <HERE>.

8.2) Poor routing

Problem – “I know a better way”

As a general rule, a navigation product will usually not take the same route that you would choose on your own. For example if you drive the same route every day, then you have learned the best way to go based on traffic patterns. The nav unit will get you there, but it will probably choose a different way.

Navigation units are not designed to show you the way to familiar destinations. If you always know the best way to go, then you do not need a nav unit! Navigation units are very handy to guide you to unfamiliar destinations. If you follow the turn-by-turn instructions, you will arrive at your destination.

Problem – “I don’t like the route”

The 7750 PLT offers flexibility in calculating a route. You can change the routing options, and you can also choose to avoid a particular road by choosing a “detour”.

For info on changing routing options, click <HERE>. For info on doing a detour, click <HERE>.

Problem – “Route Calculate Failure”

Please click <HERE> for info.

8.3) “Route Calculate Failure”

This error means that the nav unit cannot find a legal route based on the parameters of your truck. Here is an example:

EXAMPLE

In West Virginia, the maximum legal truck length is 70 feet (due to the winding mountain roads). If the you enter a length greater than 70 feet, the nav unit will not route anything into, out of, or through West Virginia. You will get a Route Calculate Failure.

Recommendations

1. Double-check your truck settings. a. Tap anywhere on the map screen. b. Tap on CONFIGURE (in the upper-right). c. Tap on TRUCK.

Make sure that you did not make a mistake when entering the length, width, or weight. For info on these settings, please click <HERE>.

2. Try setting up a new truck, and just use the default settings. If the nav unit now routes, then

you know that one of your settings was causing the problem.

3. Drive a little towards the destination and try again. This will only work if the restriction is

near your current location. If the restriction is near the destination, then you will continue to get a Route Calculate Failure.

4. If you chose to travel to a city without entering a complete address, the nav unit may have

arbitrarily chosen an address that is inaccessible by truck. Try entering an actual address.

5. If you call Cobra Customer Service at 773-889-3087, we can double-check the route for

you. Please be prepared to provide the following information:

a. Your truck info (the truck type, weights, lengths, and load type). b. The starting address (or at least the starting city). c. The destination address.

8.4) My unit will not turn on

1. Check the power switch on the back of the unit. Make sure it is switched ON.

2. Try plugging the AC adapter into the nav unit. If the nav unit turns on, then you know that it is good. If it does not turn on then there is a problem with the nav unit.

3. The cigarette socket may not have power. Try firmly pushing the cigarette plug into the socket and twist it a little.

4. The power cord may be faulty. Try a replacement power cord.

8.5) Observing satellite lock status

1. Tap anywhere on the map screen.

2. Tap on CONFIGURE.

3. Scroll to the next page and choose GPS STATUS.

Take notice of the HEALTH status as shown above. It will tell you how many satellites are locked.

At the bottom of the screen it will show individual satellite locks as follows:

White bar: The nav unit has locked onto that satellite. Gray Bar: The nav unit is in the process of locking onto that satellite. No Bar: There is no satellite reception on that channel.

The nav unit must lock onto at least 4 satellites before it will be ready to navigate.

The RESET button will reset the satellite receiver. You will immediately lose all satellite reception. It may take 5 to 10 minutes to re-acquire satellites. Do not press RESET unless you really want to reset the satellite receiver!

8.6) Auto-brightness is not working properly

The 7750 PLT will adjust the display brightness based on the time of day.

Your unit will not know the local time until it locks onto satellites, therefore the auto-brightness will not function until satellite lock is achieved.

You can also manually adjust the brightness as follows:

STEP 1 – Tap on the speaker icon in the lower-right

STEP 2 – Adjust the brightness

8.7) I do not see POI icons on the map screen

By default, the 7750 PLT will show all POI icons on the map screen. This makes for a very cluttered screen.

1. Tap anywhere on the map screen.

2. Tap on CONFIGURE (in the upper-right).

3. Tap on SHOW POI.

You may now select which categories (if any) to show on the map screen.

In order to see POI icons, you must be zoomed-in far enough.

If you do not see any icons, try zooming in.

8.8) Trouble locking onto satellites

There are several issues to check for:

1. When you purchased your nav unit, there was no satellite data stored inside. Your unit will be slow to acquire satellites until it has an opportunity to store satellite data. To let it store satellite data, simply let it run for at least 15 minutes AFTER it has locked onto satellites. After that, it should find satellites much faster.

2. Although your nav unit is very sensitive, your installation may not allow enough of the satellite signal to reach the unit. This can occur if the unit is not installed at the windshield. For best satellite reception, mount your unit at the windshield. You can also order the optional external antenna, part number EXT GPS ANT. Click <HERE> for info.

3. The antenna is located at the top of your nav unit. During installation, please arrange the mounting bracket so that it does not block the top of your unit.

To view satellite lock status in your unit, click <HERE>.

8.9) Master Reset

A master reset will clear everything in your nav unit.

All settings will be set to factory defaults.

All saved addresses will be erased.

The mileage log will be cleared.

1. Tap anywhere on the map screen.

2. Tap on SETTINGS (at the top).

3. Tap on DEVICE.

4. Scroll down until you see RESET. Tap on RESET.

5. Tap on ALL.

6. Tap on OK.

7. The nav unit should turn off.

DONE!

9.1) STAA National Network

In 1982, the U.S. Congress passed the Surface Transportation Assistance Act, which allows large trucks to operate on the Interstate highways and certain primary routes. This road system is called the “National Network”.

When driving on the National Network, you can be reasonably assured of trouble-free road access. But to make local deliveries, you will probably need to leave the National Network and drive on secondary (local) roads. You must be careful to follow local regulations.

Any nav unit can guide you on the National Network (the Interstate highway system). It is when you get onto secondary roads that the 7750 PLT will really come in handy. The 7750 PLT will calculate a legal route for you to follow.

9.2) Adjusting the volume

STEP 1 – Tap on the speaker icon in the lower-right

STEP 2 – Adjust the volume

9.3) Current Location

To view your current location:

1. Tap anywhere on the map screen.

2. Tap on FIND ON MAP (in the lower-right)

3. Tap on FIND ON MAP

You should see your GPS coordinates in the upper-left corner:

If you tap on the “i” in the lower-right corner, you will get some street information.

9.4) Observing satellite lock status

1. Tap anywhere on the map screen.

2. Tap on TOOLS (at the top).

3. Tap on GPS STATUS.

Take notice of the HEALTH status as shown above. It will tell you how many satellites are locked.

At the bottom of the screen it will show individual satellite locks as follows:

White bar: The nav unit has locked onto that satellite. Gray Bar: The nav unit is in the process of locking onto that satellite. No Bar: There is no reception from that satellite.

The nav unit must lock onto at least 4 satellites before it will be ready to navigate.

The RESET button will reset the satellite receiver. You will immediately lose all satellite reception. Do not press RESET unless you really want to reset the satellite receiver!

9.5) Elevation

From the map screen, tap on the bottom tab and then tap on “Trip CPU”

You can now see the elevation:

The elevation accuracy is approximately ± 150 feet.

9.6) Power light status

There is a power light at the top left corner of the GPS. The status of the light is as follows:

MAIN

POWER

Off Plugged in Charging RED

9.7) Backing up the Address Book

The 7750 PLT has a built-in function for backing up the Address Book. To use this function, you need to plug a blank Micro SD card into the slot on the side of your unit. The address book will be saved to the Micro SD card.

Any brand of Micro SD card should be fine. The address book takes very little space, so even the smallest Micro SD card that you find will be plenty big enough. It will not get filled up. Ample space will also be available for saving the mileage log.

To save the address book:

1. Tap anywhere on the map screen.

2. Tap on TOOLS (at the top).

3. Tap on BACKUP / RESTORE.

4. Tap on BACKUP ADDRESS BOOK.
