Identify the Issue
The cornerstone to resolving the issue of your GPS not working in a Jeep Grand Cherokee is identifying the root cause. GPS malfunctions can be broadly categorized into software-related and hardware-related issues. To diagnose what’s affecting your GPS, here are some more in-depth explanations of the common symptoms:
Software-Related Issues
- Screen Freezing: If the GPS screen becomes unresponsive or “freezes,” this is often a software-related issue. This could be due to outdated firmware or software glitches.
- Incorrect Location Data: When the GPS displays inaccurate location details, the issue often lies in the mapping software. This can happen if the software hasn’t been updated recently.
- Error Messages: Receiving error messages like ‘Cannot Connect to Satellite’ indicates a software problem. Software updates or soft resets usually solve this.
Hardware-Related Issues
- Failing to Connect to Satellites: Although this can be a software issue, it often indicates a malfunctioning GPS antenna. Physical damage or obstruction could be the culprit.
- Screen Artifacts: Unusual lines or colors on the screen typically indicate a hardware problem, specifically with the display unit.
- No Power: If the GPS system won’t turn on at all, the issue is likely hardware-related. This could be due to faulty wiring or a problem with the power supply to the GPS unit.
Check for Software Updates
Old software can be a silent culprit. If your GPS software is outdated, features may stop working or become less accurate. Updating your GPS software can fix existing bugs and improve functionality. For detailed instructions on how to do this, refer to your Jeep Grand Cherokee manual or visit the official Jeep owners’ site for software updates.

Inspect Wiring
Physical issues like loose or damaged wiring can disrupt the GPS system. You’ll need to open the GPS console carefully to inspect the wires. Check your vehicle’s manual for specific instructions on how to access the wiring safely. If you’re not comfortable doing this yourself, consider seeking the help of a certified Jeep service technician.
Perform a Soft Reset
A soft reset is an effective way to resolve minor glitches that might be causing your GPS not to work in your Jeep Grand Cherokee. Just like rebooting a computer or smartphone can resolve issues, a soft reset can often clear the temporary software or firmware glitches that could be hampering your GPS system.
What is a Soft Reset?
A soft reset essentially involves restarting the vehicle’s electronic systems without losing any saved settings or data. This can refresh the system and clear out minor bugs that might have crept in during use.
Steps to Perform a Soft Reset
- Turn Off the Ignition: Safely park your Jeep Grand Cherokee in a secure location, away from traffic. Turn off the ignition and remove the key or fob.
- Wait: Allow the vehicle’s electronic systems to shut down completely. Wait for at least five minutes to ensure that all systems have powered down.
- Restart the Vehicle: Insert the key back into the ignition or place the key fob near the start button, depending on your model. Turn on the ignition but don’t start the engine just yet. Wait for the dashboard lights and electronic systems to initialize.
- Check the GPS: Once the systems are back up, turn on the GPS and see if the issue persists. If the GPS is functioning correctly, then the soft reset was successful.
Consult the Dealer or a Certified Technician
If you’ve tried the above steps and your GPS is still not working, it may be time for professional intervention. Consult your local dealer or a certified Jeep technician for a thorough diagnosis and repair. Services usually include software diagnostics, hardware checks, and possibly parts replacement. The Automotive Service Excellence (ASE) website is a reliable resource for finding certified professionals.
