Q: Why is there no picture?

Q: Why can’t the unit receive satellite signals or orient itself?
A: The unit may be obstructed by buildings or metal objects. Please make sure to use the unit outside and where it has a clear view of the sky.
Q: The unit can receive signals now, but the signals received are not stable. Why?
A: The built-in rechargeable battery is weak; use the adapter to supply power or charge the battery. The unit may be obstructed by a material such as heat insulation, please remove the obstruction. The unit may be titled too far; please hold the unit upright. If the system software fails to function by chance, please restart the unit again.
Q: Why is the altitude on my GPS different than the altitude on my altimeter?
A: Keep in mind that your altimeter does not measure altitude. Your altimeter is calibrated to display a certain change in altitude based on a change in air pressure.
Q: When I have maps from different MapSource products loaded for the same place, I only see one map in my GPS. To see some maps, I have to turn others off in the GPS unit display. Why?
A: There is a hierarchy in the MapSource products. Map data often comes from different vendors, and if the vendors blended the data, it would be difficult to use. You can manage maps in your GPS unit so the subordinate maps will show when you need to see them.
Q: When I insert a non Nextar-map SD card and select the main menu "Navigation" item, the unit can not be operated and it freezes. Why? (Reference to for product Q4-01)
A: The unit may not find the correct path of the executable file of the navigation software or the navigation software is not supported. Always use the navigation software that came with your unit. Third party software is not guaranteed to work properly with the unit.
Q: Why is the volume too low to hear?
A: Check if the volume was turned down or Muted, and if so turn up the volume or turn on the sound output.
Q: Why does the unit give wrong directions?
A: There are numerous possible causes. First, the GPS may not be receiving a strong enough signal to be able to both calculate your exact position and guide you the right way in a timely manner. Another possible cause is that the map data is becoming outdated or that some streets are newly constructed, so the unit does not work with the greatest efficiency. Normally, GPS navigation software is equipped with an automatic re-routing feature. When the road or street does not exist or you go to the wrong way, the unit will recalculate the route for you and continue to guide you to the destination.
Q: It freezes on the "loading" screen. Why?
A: Since the operating system and navigation software are preloaded into the internal flash memory of the GPS, the freezing may either be software or hardware failure. First, press the "Reset" button or push the stylus into the "Reset" hole, to see if the navigation software can load successfully. If the program still does not load, then the software may be corrupted. Also, if the internal memory fails to read or write and the software cannot load properly, it may be caused by hardware failure. In either case, please return the unit for exchange or repair to the retail location from which you purchased it, or contact us for further assistance.
Q: Where can I buy the Canadian/ European maps?
A: To update the existing map or buy a new country map for your Nextar product, contact the retail store from which you purchased the unit, or contact Nextar for any available maps. Our products are usually pre-loaded with USA/Canada maps, depending on the model.
Q: Is there a particular manufacturer of the Micro SD cards that is recommended for use with the GPS units?
A: Nextar recommends brand-name memory cards because the quality and stability can be ensured to work well with our product.
Q: What is the optimal resolution of the display?
A: If the display size is 4.3", the optimal resolution is 480X272 (RGB). If the display size is 3.5", the optimal resolution is 320X240 (RGB).
Q: Why do I sometimes find map errors in Nextar products?
A: There are inevitably some road changes, as well as human error or subjectivity in the creation of a digital map. The maps must be constantly maintained to keep the level of error as low as possible. Nextar uses NAVTEQ maps, and we focus on supplying updated maps to our valuable customers.

Q: Why can’t the battery be used after being idle a few days with a full charge?
A: In common conditions, the battery would last about 4-8 days after it is fully charged and turned off. The charge will drain over time, whether or not the unit is in use. Please charge your battery and try again.
Q: Why can’t the unit be charged?
A: Please make sure your AC adaptor or car adaptor is properly connected to the main unit and that the adaptor is receiving AC power. If problem persists, there may be a hardware problem with the rechargeable battery. Call our technical support center at 1-888-849-0846 for further support.
Q: Why does the battery drain so fast and fail to charge in the car when I plug it in?
A: Please try to charge your unit with the AC adaptor again. If it charges, test your car adaptor. If the car adaptor works, you may need to repair your battery.
Q: Why won’t the unit turn on when it is being charged?
A: If the unit has not been used for a long period, the battery may run out of power completely. When the battery is weak or totally dead, there may not be enough power to turn the unit on immediately. Keep charging the unit a while longer, then try to turn it on again later.
Q: Why does the unit keep going back to International time when I try to set it to my local time zone?
A: Make sure you have saved your preferred settings before you exit the menu.
