However, let us understand how the GPS of your Grand Cherokee operates, why it malfunctions, and ways to fix it.
Understanding How The GPS Works In Jeep Grand Cherokee
Before we proceed further in finding the causes of your jeep grand Cherokee’s GPS not working, we need to take a look at how the GPS connection works in your Jeep.
The Connection Of GPS With Satellites
GPS means Global positioning system. It’s a device that aids you to track different locations, with the help of an external antenna that receives signals.
Also, the GPS on your jeep grand Cherokee works hand in hand with a mesh of satellites which is about 24 satellites as far as 20,000km altitude in the earth’s circuit. Thus, these satellites make it possible to calibrate the GPS device’s position and provide precise location data for your car.
However, reception issues occur mostly in hilly areas surrounded by land. And they are caused by the need to concurrently gather information from four different satellites to have factual information.
Connection Of Playback Screen With A GPS
The playback screen and GPS are connected, however, the GPS has a control button that interacts with and configures the gadget in the car.
GPS Connection With The Radio Antenna
The GPS uses an external radio antenna which helps to improve GPS reception. This makes your jeep’s GPS to be seen as being superior and more exact when compared to a smartphone’s GPS.
There have been several complaints from jeep grand Cherokee owners about their non-functional GPS. That’s why we want to discuss different reasons why your GPS is not working or giving you inaccurate information concerning a location.

- When The GPS Cannot Locate The Signal
When the GPS signal reception is poor or cannot locate any signal at all or are experiencing recurrent bugging, it’s a sign that you have a faulty antenna. The antenna helps to facilitate the smooth running of the GPS.
If the antenna fails to work, the GPS will not respond, and this will occur if your antenna is worn out, damaged or poorly/wrongly installed.
- An Older Version Of The Uconnect
If your GPS detects the wrong location all the time, you might need a system upgrade. Your Uconnect software is likely an older version that needs an update. Note that an update may spring up issues and may also alter some information.
- A Frozen GPS Screen
There were several complaints from owners of the Grand Cherokee about a frozen GPS screen, which made it stop working. This is an electrical fault or a compromised operating system.
- A Wrong Navigation Message By The GPS
When you receive a wrong navigation message from the GPS of your Jeep, which can occur because of a disconnected satellite from your Jeep Grand Cherokee GPS. Also, outdated cartography, a wrong map, or a road network that keeps evolving will send a false navigation message through the GPS.

If the head unit reset doesn’t respond, you may have to purchase another head unit, costing about $400 to $600. Also, check for a burnt or damaged fuse since it’s more of an electrical fault and replace it.
