If your OBD2 device is not reporting GPS location data, several factors could be affecting the signal reception. Below, we outline potential causes and troubleshooting steps to help resolve the issue.
1. Verify Vehicle Data Reporting
Before troubleshooting the GPS issue, ensure that your vehicle is reporting other data (such as fuel level or odometer). If no data is being transmitted, the problem may be unrelated to GPS. Observe the light pattern on the device to identify connectivity issues such as a missing cellular signal. In such cases, please reach out to our support team for assistance.
2. Ensure the Vehicle is in an Open Sky Environment
GPS signals require a clear line of sight to satellites. If your vehicle is parked in a garage, under a carport, or in an underground location, the GPS reception may be blocked. Move the vehicle to an open area and check if the GPS starts reporting.
3. Check for Athermic or UV-Blocking Windshields
Some vehicles, particularly high-end, electric, or hybrid models, come with athermic or UV-blocking windshields that can interfere with GPS reception. To check if your vehicle has such a windshield, look up the specifications or consult the manufacturer documentation. If your windshield blocks GPS signals, you may need to position the device in a different location within the vehicle.
Potential Solution:
Many vehicles with athermic windshields have a "communication hole," often near the central rearview mirror, where GPS signals can pass through more easily. Try relocating the device near this area if possible.
4. Assess the OBD2 Dongle Placement
The location of the OBD2 device within the vehicle can impact GPS reception. Metal components, such as the dashboard, chassis, or other shielding materials, may block the GPS signal. If the dongle is installed in a position with limited exposure, it may struggle to receive signals.
Potential Solution:
Consider using an OBD2 extension cable to reposition the device in a more open location where GPS reception may improve.
5. Check for Electromagnetic Interference
Certain electronic devices inside the vehicle can generate electromagnetic interference, disrupting the GPS signal. Common culprits include:
Wireless chargers
Dashcams
LCD or touchscreen displays
Power inverters
Potential Solution:
If possible, temporarily unplug these devices and check if the GPS signal improves. In some cases, even a nearby USB drive may interfere with the signal due to emissions on the same frequency band as the dongle.
