OEM Navigation Control Module for 2000-2002 Buick, Cadillac, Chevrolet, GMC, Oldsmobile, & Pontiac

When buying a navigation control module, look for:

• Compatibility: Make sure the module is designed to work with your specific vehicle year, make, and model.
• Condition: If buying a used module, check its physical condition. Look for signs of damage or corrosion.
• Warranty: A warranty can protect you if the module fails shortly after you buy it.
• Reputation: Buy from a trusted seller with a good reputation for selling quality parts.

Quality indicators:

• OEM Markings: Original Equipment Manufacturer (OEM) parts will have the manufacturer's logo and part number.
• Testing: Ask if the module has been tested to ensure it's working properly.
• Cleanliness: A clean module is usually a sign that it has been well-maintained.

Typically included with the part:

• The navigation control module itself.
• Sometimes, mounting hardware may be included.
• Usually, instructions or wiring diagrams are NOT included.

Difficulty level: Medium

Estimated time: 1-2 hours

Special tools needed:

• Socket set
• Screwdrivers
• Trim removal tools (optional)

Critical steps and tips:

1. Disconnect the negative battery cable before starting. This prevents electrical shocks.
2. Locate the navigation control module. It's often behind the dashboard or in the trunk.
3. Disconnect the wiring harness from the module.
4. Remove the old module and install the new one.
5. Reconnect the wiring harness.
6. Reconnect the negative battery cable.
7. Test the navigation system to make sure it's working properly.

DIY is possible for mechanically inclined individuals. However, professional installation is recommended if you're not comfortable working with electrical systems.

• Used OEM: These are genuine factory parts that have been tested and inspected. They offer excellent value at a lower price than new parts.
• New Aftermarket: These are brand new parts made by third-party manufacturers to meet or exceed OE specifications.

• GPS Antenna: The GPS antenna receives signals from satellites. A faulty antenna can cause navigation problems.
• Wiring Harness: Damaged or corroded wiring can prevent the module from working properly.
• Navigation Screen: A faulty screen can display incorrect information or not work at all.
• Vehicle Speed Sensor (VSS): The VSS provides speed information to the navigation system. A faulty VSS can cause inaccurate location data.

Replacing related parts at the same time can prevent repeat failures by addressing underlying issues that may have contributed to the original module's failure. For example, a faulty GPS antenna could have damaged the module. Replacing both ensures the system works correctly.

The navigation control module typically lasts 7-10 years.

Factors that affect longevity:

• Environmental Conditions: Extreme temperatures and humidity can shorten the module's lifespan.
• Electrical System Health: A healthy electrical system protects the module from voltage spikes and surges.
• Driving Habits: Rough driving can cause vibrations that damage the module.
• Maintenance: Keeping the vehicle clean and dry can help prevent corrosion.

• Budget: $50 - $150
• Mid-Range: $150 - $300
• Premium: $300+

Labor costs for installation can range from $75 to $200, depending on the shop and the complexity of the job.

Total job cost estimates:

• Budget: $125 - $350
• Mid-Range: $225 - $500
• Premium: $375+

Some vehicles from this era are known to have issues with water leaks that can damage the navigation control module. Check for signs of water damage before replacing the module. Also, some models may require reprogramming after the new module is installed. Consult a qualified technician for details.

1. Turn on the ignition and start the vehicle.
2. Check that the navigation screen powers on and displays information.
3. Enter a destination and verify that the system calculates a route.
4. Drive the vehicle and confirm that the navigation system tracks your location accurately.
5. Listen for any unusual noises or error messages.
6. Test all the buttons and controls on the navigation system to make sure they work properly.

If everything works as expected, the installation was successful. If you experience any problems, consult a qualified technician.

Q: How do I know if my navigation control module is bad?
A: Common signs include a blank screen, freezing, incorrect location data, or unresponsive buttons.

Q: Can I replace the navigation control module myself?
A: It's possible if you're comfortable working with electrical systems. However, professional installation is recommended.

Q: Will a used navigation control module work in my car?
A: Yes, as long as it's compatible with your vehicle's year, make, and model.

Q: Do I need to reprogram the navigation control module after installing it?
A: Some models may require reprogramming. Check your vehicle's service manual or consult a qualified technician.

Q: What's the difference between a used OEM module and a new aftermarket module?
A: A used OEM module is a genuine factory part that has been tested. A new aftermarket module is made by a third-party manufacturer. Both can be good options.
