Troubleshooting an Automotive Traffic Issue with the HD Traffic Mount

The HD Traffic Mount is purchased separately from your device. If you are instead using dēzl™ App or with a compatible Android phone or iPhone, see:

• Troubleshooting dēzl App Traffic on a Compatible dēzl.
  

Troubleshooting Traffic When Using the HD Traffic Mount:

See the troubleshooting steps below if you have a Garmin device with the HD Traffic Mount but are not receiving any traffic information.

NOTE: If your device was preloaded with full map coverage (i.e. North America), and full map coverage is not installed, you may not receive traffic updates on your device. See Maps Missing After Updating Maps on a Full Coverage Automotive Device for more information.

Try the Following Steps to Troubleshoot Traffic: 

1. Confirm you're using the device in a traffic coverage area based on the Traffic Service you are using

   • See Interpreting the HD Digital Traffic Map.
   • HD Digital Traffic Coverage Map.

2. Verify you are not in an area affected by the Current Traffic Outages

   • July 24, 2025

     • USA Little Rock, AR: KUAR RDS off - Total Market Outage
     • USA Spokane, WA: KPBX HD and RDS off - Total Market Outage
     • USA West Palm Beach, FL: WMBX RDS off - Reduced Service Area

     RDS = Garmin Traffic | HD = HD Digital Traffic.

3. Confirm external power is being supplied to the vehicle power cable and HD Traffic Mount. The LED light on the top of the cable should be lit.
   

4. Update the device software by following steps in Wireless Map and Software Update Instructions

It is also possible that the traffic service has been disabled on your device which will result in traffic not working.

To Confirm Whether the Service is Enabled:

1. Connect the device to power using the vehicle power cable
2. Open the Settings menu
3. Touch Navigation
4. Touch Traffic

If traffic is disabled, touch Traffic to enable it.
