The Navigation Center appreciates your reports regarding service degradations, outages, or other incidents or anomalies. Please answer the questions below. Some fields are required for submission, but all personal data will be kept private and will only be used to contact you in the event that we need more information or if clarification is required. Please be as complete as possible when reporting an incident. Thank you!

Note about vehicle navigation systems: If you are having problems with information such as location names, addresses, closed highway exits or other mapping data, it is likely that your GPS's mapping software is outdated or obsolete. The Navigation Center does not develop, control, nor repair the mapping software or maps in your vehicle navigation system. We suggest you contact your car dealer or the manufacturer of your GPS unit or navigation system.

Mapping Data Errors: If you wish to report an incorrect address, report or request a change to the address for a business or home, or add an address, please submit your corrections to the Tele Atlas website.

If you are experiencing GPS issues relating to positioning, navigation, timing or signals please proceed to and fill out a GPS outage report starting with the form below.
