Frequently Asked Questions
Why can't I find my address in the software on my NAV300 when I enter my city?
The map data on your NAV300 uses geographical definitions for addresses, which may differ from post office address. Inconsistencies in this area are rare but they do occur. In many cases, the street address may be found by using a neighboring city. You may also find it by using a zip code instead of the city.
Why am I unable to select Alaska or Hawaii in the region field of the address screen on my NAV300 unit?
Alaska, Hawaii, and Puerto Rico are all in separate maps in your NAV300 unit. You must have the appropriate map selected for any of these regions in the address. To change the map, select map from the main menu.
If I'm having trouble finding a street on my NAV300 unit how should I proceed?
(Examples: W Main St or N Park Rd) To make street input easier on your NAV300, try entering only the "basename" portion of the street. For example "Main" instead of W Main Street or "Park" instead of N Park Rd. The software will prompt the user for the correct street.
When calculating a route to a POI, why does the device tell me the destination is in a restricted area?
Some POI destinations are physically located within a pedestrian-only zone in the map database. This includes large buildings where the POI is at the center of the building (shopping malls, sports arenas, etc.). The directions given will take the user to the requested location.Please follow all traffic laws in your area and never drive into a pedestrian zone or other area prohibited for use in a vehicle.
Why does the software on my NAV300 unit add a zip code when I enter a city into the address field? After I finish entering the rest of the address (street name and house number), the Zip code changes.
When a city is entered in your NAV300 unit without a zip code, the software shows the zip code specified for the city center - 90012 is used for Los Angeles. Once the complete address is known, the accurate zip code for that particular address will be shown - 90028 for the intersection of Hollywood and Vine in Los Angeles.
Why doesn't my NAV300 show a city when I enter a zip code?
In many cases, a zip code may include streets that fall in more than one city. To avoid confusion with listing multiple cities, only the zip code is shown.
How is the destination time determined on my NAV300 unit?
Arrival times on your NAV300 unit are calculated based on data from the map. These are typically based on speed limits, road classifications, etc. Factors such as traffic flow, weather, road conditions, etc. cannot be accounted for and will influence the time to destination. The optional Traffic Message Channel (TMC) device will provide a more accurate estimate.
How does the NAV300 calculate an Estimated Time of Arrival (ETA)?
Estimated Time of Arrival (ETA) values are based on time zone settings specified in the software. Verify that you have set the correct time zone by going to settings -> Time Zone. ETA times are calculated based on data from the map. These are typically based on speed limits, road classifications, etc. Factors such as traffic flow, weather, road conditions, etc. cannot be accounted for and will influence the time to destination. The optional Traffic Message Channel (TMC) device will provide a more accurate estimate.
I received a Read File Failed error on my NAV300 unit, what does that mean?
If you receive a Read File Failed error on your NAV300 unit select "ok" to remove the error. This is not a fatal error and navigation functionality will continue as normal. This can occur if the device is turned off while reading from the SD card, reading the map at startup, searching for points of interest (POI) or calculating a route.
Why did I get an error message on my NAV300 unit stating that a map could not be found?
If you get an error message on your NAV300 unit stating that a map could not be found, try checking to see if the SD card is properly inserted and reboot your system. Using an SD card adaptor (sold separately) check that the map files are still on the SD card, copy all files from the backup folder on the backup DVD to the SD card and insert SD card back into the device. (SD card adaptor not included).
SD Card directory structure should look like the following:
Why do I get an error message on my NAV300 unit stating the route cannot be calculated?
If you get an error message on your NAV300 unit while trying to calculate a route, it may mean that your current position is not on a road and the software does not know where to begin (typically a large parking lot or rural area). Drive to the nearest road and start the calculation again.
While trying to calculate a route on my NAV300 unit what do I do if I get an error message stating that the destination is in an isolated area?
If you get an error message on your NAV300 unit that states the destination is in an isolated area, this indicates that the destination is in an area that is not on a road. Select a point closer to the road and try the calculation again. Check your settings, for example, if your destination is located on an island and you have "ferries" de-selected, you will receive this error message.
What are the differences between vehicle, bicycle, and pedestrian in the speed profile setting of my NAV300 unit?
On your NAV300 unit, the vehicle profile is used for routing while in a vehicle and enforces all standard traffic laws (1-way streets, turn restrictions, etc) and bases time estimates on road speed limits. The bicycle profile is designed for usage while on a bicycle and removes restrictions for traffic laws but prohibits travel on interstates. Time estimates are also increased to match average bicycle speeds. The pedestrian profile is similar to the bicycle mode but lowers the time estimates further to match average walking speeds.
What is a TMC and how do I use it?
TMC stands for Traffic Message Channel and is a traffic information module. To use the TMC service, you must purchase the optional TMC receiver accessory. The TMC receiver accessory is supplied with a lifetime subscription to the traffic service. Simply load the software per the instructions, connect the receiver and antenna.
What is the threaded insert for on the back of the NAV300? Am I missing a threaded fastener from my kit?
The threaded insert on the back of the NAV300 unit is for an optional Motorcycle Mount Accessory.
How can I view the software in French or Spanish on my NAV300 unit?
Language settings on your NAV300 unit can be found in the main device menu under settings. The navigation software will adjust itself accordingly. Note that French, Spanish, and English are the only languages supported. If any other language is selected, the device will continue to use English.

Why doesn't my computer see the SD Card adaptor (reader/writer) I purchased?
I reformatted my SD Card and copied the files from the DVD, now the NAV300 has no voice and won't route. What’ wrong?
Why doesn't my NAV300 run after I restored the files to my SD Card from the DVD?
Check the files on your SD Card, if you copied the folders such that the "MN6" folder is not visible to the NAV300, it doesn't know what to do. Copy all DVD (backup) files to the SD Card "Root Directory." Do not copy the "Manual" folder to the SD Card.
SD Card directory structure should look like the following:
How big of an SD Card will the NAV300 support?
How do I open the navigation application on my NAV300 unit if it is grayed out?
If you cannot open the navigation application and the NAVI button on the main menu is gray, verify the SD card is inserted and it has all applicable software and maps. If needed, copy the files over from the backup DVD. Reboot after inserting NAV SD Card.
Why isn't my NAV300 unit detecting a GPS signal?
The icon stays red when selected or says GPS is not available. If your NAV300 unit does not detect a signal, make sure the device has a clear view of the sky and the GPS antenna is extended. Some vehicles have heated/metallic windshields that degrade GPS signal reception. If you have just turned on your unit, allow additional time to find the signal. If you are in an urban area (New York City, Chicago), move away from tall buildings or other obstructions. Voice prompts may not match map. If you are still having problems, you may need to purchase an external antenna.
Why can't I get a valid GPS position in a large city?
If you are in a large city and are having trouble getting a signal from your NAV200 unit you may be able to obtain a signal simply by moving around to a different location. Large metropolitan areas can create an "urban canyon" which disrupts the GPS signals from the various satellites. This is caused by multiple signals from the same satellite bouncing off of the various buildings and confusing the GPS receiver.
Why can't I find a point of interest (POI) using my NAV300 unit?
The current map on the NAV300 unit includes approximately 1.6 million POIs in a variety of categories. We strive to keep the database information as up to date as possible however some inconsistencies may occur over time. These changes will be reflected in future updates to the map database.
Why does the route the NAV300 calculates differ from my preferred route for going from point A to point B?
Calculation on the NAV300 unit is based on a complex algorithm that compares each road segment with respect to speed, traffic flow, number of lanes, etc. In some cases, the suggested route may follow a different set of streets than what you are used to. This is correct behavior and follows the rules specified in the database. Routes will also change depending on if you have selected fastest or shortest route or have prohibited use of interstates, ferries, or tollways. Route settings can be changed in the settings menu by going to Settings -> Routing Options.
Why don't I receive TMC messages on my NAV300 unit if I have an active TMC service?
TMC service is only supported on your NAV300 unit in specific metropolitan areas. You must have a valid GPS signal to begin receiving TMC messages because GPS signal sends time information used to verify your TMC service. TMC messages are broadcast over FM radio frequencies. Be sure the antenna is attached to your TMC receiver and fully extended for best reception.
How do I delete my my favorites / recent destinations?
To remove favorite/recent destinations, after selecting the entries to be removed, the NAV300 must go through an “orderly” shutdown, by pressing the "Quit" softkey and exiting Navigation. Simply pressing the "Power Button" will not work.
Why am I asked for a pin each time I try to use my phone with my NAV300?
