Infiniti Navigation Third Generation Dvd Map Update Version 12

Let's dive into the specifics of the Infiniti Navigation Third Generation DVD Map Update, specifically Version 12. This update, while now several years old, represents a significant leap in in-car navigation technology for its time and knowing its ins and outs can be incredibly valuable for owners of these older vehicles, whether you're looking to breathe new life into a classic Infiniti or troubleshoot existing navigation issues. This guide assumes you're comfortable with basic automotive electronics and data handling.

Understanding the Third Generation Navigation System

Before we get into the nitty-gritty of the Version 12 update, it's crucial to understand the architecture of the Infiniti Third Generation Navigation System itself. This system typically utilizes a DVD-based map data storage. That means the map information isn't stored on a hard drive or flash memory, but rather read directly from a DVD placed in the navigation unit, generally located in the trunk or under a seat. This system is characterized by:

DVD-Based System: The navigation unit physically reads map data from a DVD. This is a key distinction from more modern systems.
Proprietary Format: The map data is stored in a proprietary format specific to the Infiniti navigation system. You cannot simply burn generic map files onto a DVD and expect it to work.
Limited Functionality compared to Modern Systems: Expect slower processing speeds, less detailed graphics, and fewer Points of Interest (POI) compared to modern smartphone-based or integrated navigation systems.
Regular Updates Required: Roads change, businesses open and close. Regular map updates are essential to maintain accuracy and relevance.

What's New in Version 12?

Version 12 of the Infiniti Navigation Third Generation DVD Map Update brought several improvements over previous versions, though they are incremental considering the system's age. Key upgrades typically include:

Updated Road Network: This is the primary benefit. Version 12 incorporates changes to the road network, including new roads, highway extensions, and rerouting of existing roads.
Expanded Points of Interest (POI) Database: New businesses, restaurants, gas stations, and other points of interest are added to the database, making it easier to find destinations.
Improved Routing Algorithms: While not a complete overhaul, Version 12 often tweaked the routing algorithms to provide more efficient and accurate routes based on the updated road network. This could lead to slightly faster travel times or avoidance of newly congested areas.
Minor Bug Fixes: Navigation systems, like any software, can contain bugs. Version 12 likely included fixes for minor glitches and errors reported by users of previous versions.

The magnitude of these improvements will vary depending on your location and the extent of road network changes in your area. If you live in a rapidly developing area, the benefits of Version 12 will be more noticeable.

The Update Process: A Step-by-Step Guide

Updating the navigation system with Version 12 is a relatively straightforward process, but it requires careful attention to detail. Always consult your vehicle's owner's manual and the instructions included with the DVD update for specific instructions and warnings. Here's a general overview:

Obtain the Correct DVD: This is crucial. Ensure you are purchasing the correct DVD update for your specific Infiniti model and navigation system generation. Using the wrong DVD can potentially damage the navigation unit. Verify the part number and compatibility before purchasing.
Locate the Navigation Unit: As mentioned earlier, the navigation unit is typically located in the trunk or under a seat. Refer to your owner's manual for its precise location.
Eject the Existing DVD: Power on your vehicle and the navigation system. Use the eject button on the navigation unit to remove the old map DVD.
Insert the New DVD: Carefully insert the Version 12 DVD into the navigation unit. Ensure the DVD is inserted correctly with the label facing up.
Follow On-Screen Prompts: The navigation system should automatically detect the new DVD and begin the update process. Follow the on-screen prompts carefully. The system may ask you to confirm the update or enter a security code.
Do Not Interrupt the Update: This is extremely important. Do not turn off the vehicle, remove the DVD, or interrupt the update process in any way. Doing so can corrupt the navigation system software and potentially require professional repair. The update process can take anywhere from 30 minutes to an hour, depending on the system.
Verification: Once the update is complete, the navigation system should restart automatically. Verify that the update was successful by checking the map version in the system settings. Also, test the navigation functionality to ensure everything is working correctly.

Important Note: Some Infiniti models may require a specific sequence of button presses or a diagnostic mode to initiate the update process. Consult your owner's manual for model-specific instructions.

Troubleshooting Common Issues

While the update process is usually smooth, some users may encounter issues. Here are some common problems and potential solutions:

"Disc Read Error": This error usually indicates a problem with the DVD itself, the navigation unit's DVD drive, or a compatibility issue.
- Solution: Try cleaning the DVD with a soft, lint-free cloth. Ensure the DVD is not scratched or damaged. If the problem persists, try a different DVD or consult a professional. The DVD drive itself might be faulty and need repair or replacement.
"Incorrect Disc": This error indicates that the DVD is not compatible with your navigation system.
- Solution: Verify that you have the correct DVD for your specific Infiniti model and navigation system generation. Check the part number and compatibility information.
"Update Failed": This error indicates that the update process was interrupted or encountered a problem.
- Solution: Ensure the vehicle's battery is fully charged and that the vehicle is in a well-ventilated area. Restart the update process from the beginning, ensuring that you do not interrupt it. If the problem persists, consult a professional. The navigation system's firmware might be corrupted and require reflashing.
Navigation System Not Working After Update: This is a serious issue that could indicate a corrupted update or a hardware problem.
- Solution: Try disconnecting the vehicle's battery for a few minutes to reset the navigation system. If that doesn't work, consult a professional. The navigation system might need to be reprogrammed or repaired.

Alternatives to Updating the DVD Map

Given the age of the Third Generation Navigation System, and the limited availability (and potentially high cost) of the Version 12 DVD, it's worth considering alternatives. These options often provide more up-to-date maps and features.

Smartphone Integration: Many aftermarket head units offer smartphone integration features like Apple CarPlay and Android Auto. These systems allow you to use your smartphone's navigation apps (e.g., Google Maps, Waze) on the car's display. This is often the most cost-effective and feature-rich solution. Replacing the head unit might seem daunting, but it's a popular modification and plenty of resources are available online.
Portable GPS Units: A portable GPS unit, such as a Garmin or TomTom, can be a simple and inexpensive way to get updated navigation. These units typically have lifetime map updates included.
Aftermarket Navigation Systems: Some aftermarket companies offer complete navigation systems designed to replace the factory system. These systems often have more features and better performance than the original system.

Conclusion

Updating your Infiniti's Third Generation Navigation System with Version 12 can provide some improvements in map accuracy and POI data. However, given the age of the system and the availability of alternative navigation solutions, it's important to weigh the costs and benefits carefully. If you're comfortable with basic automotive electronics, the update process is relatively straightforward. However, if you encounter any problems, it's always best to consult a professional to avoid damaging the navigation system. Keep in mind that newer technologies offer substantial advantages in terms of features, speed, and map accuracy. Modernizing your navigation experience could be a worthwhile investment for enhanced driving.

Remember to always prioritize safety and consult your vehicle's owner's manual and the update instructions for specific guidance. Happy navigating!
