For the installer
The GTM 10 FM TMC Traffic Receiver installs between a vehicle’s radio and its antenna cable. Carefully read this Installation Sheet and follow the instructions to install the GTM 10 in the vehicle.
GTM 10 overview
The GTM 10 has two cable connectors that allow it to be installed in series between the antenna and radio. Do not open the GTM 10 or loosen the case screws.
in: In from antenna. Connect the antenna adapter here.
out: Out to radio. Connect the radio adapter cable here.
leD: displays the signal status.
Mini-UsB cable: 1.5-meter built-in cable to connect to a Garmin GPS
device.
step 1: Prepare the radio
Test: Before installation, test the vehicle’s radio to ensure that the antenna is functioning properly and the radio can receive all normal FM signals. If the antenna functions improperly, the GTM 10 may not work properly. Consult the owner about continuing with installation.
Remove the trim panel and other parts of the dashboard to access the vehicle’s radio antenna cable. You may need to remove the radio as well. Detach the antenna cable.
step 2: Choose the appropriate Cables
The GTM 10 ships with several adapter cables. Each cable contains at least one Farkas connector for connecting to the GTM 10 In/Out receptacles. Except for the dual-ended Farkas cable, the cables are grouped in pairs: for each cable with a male end (plug) there is a matching cable with a female end (receptacle).
European and UK packages include one cable that has two Farkas connectors, one pair of ISO cables, and one pair of Motorola cables. The US package includes one cable that has two Farkas connectors, one pair of Motorola cables, and one pair of GM cables.

-
ISO Male (Plug)
-
ISO Female (Receptacle)
-

-

-
GM Male (Plug)
-
GM Female (Receptacle)
To select the proper pair of cables to use, match the adapter cable male end (plug) to the vehicle’s radio antenna cable plug. Use that pair of cables for the installation. If the antenna has a Farkas connector, use the dual-ended Fakra cable between the GTM 10 and the radio.
Step 3: Connect to the Radio
The GTM 10 connects in series between the antenna and radio, using the adapter cables chosen in Step 2.
-
. Connect the antenna plug to the appropriate female (receptacle) adapter cable. Connect the Farkas plug to the In connector on the GTM 10. The Farkas plug locks firmly in place.
If the antenna cable has a Farkas connector, no adapter cable is needed between the antenna cable and the GTM 10 In connector. Connect the Farkas antenna cable directly into the In connector of the GTM 10. Then use the supplied dual-ended Farkas cable to connect the GTM 10 to the radio, as described below. -
Connect the Farkas connector of the adapter cable to the Out connector of the GTM 10. Connect the male (plug) adapter cable into the radio receptacle, as shown below.
TEST: Turn on the vehicle’s radio. If sound from an FM radio station can
be heard, the GTM 10 and its
cables are properly connected. If no sound is heard, the GTM 10 is not
connected correctly. Check that all
cables are locked into place and free of obstructions. If the connections
are secure, make sure the chosen
adapter cables are correct for the vehicle.
Step 4: Connect to the GPS Device
Refer to question 1 on the Owner Questionnaire for the owner’s instructions on how to route the cable up to the GPS. Route the mini-USB cable from behind the radio on the passenger’s side of the vehicle up to the GPS device. If possible, thread the cable through an existing opening in the glove box or trim panel. Thread enough cable through the opening to reach the GPS device. Do not cut the mini-USB cable.
If the mini-USB cable is not long enough to reach the GPS device, a 2-meter extension cable is available for purchase from a Garmin dealer or from the Garmin Web site at http://www.garmin.com/products/gtm10.
Step 5: Test the GTM 10
Test the GTM 10 for proper installation and service reception. Connect the mini-USB connector to the Garmin GPS device, if you have access to the GPS.
- Observe the LED: Turn on the GPS device. Service reception is indicated by the solid green light, which may take up to five minutes to appear for initial data acquisition.
| Yellow dot-dash flashes: waiting for initial country code, automatically supplied by the Garmin GPS device.
---|---
| Yellow fast flashes: searching table for active entry
| Red/Green flashes: scanning for new TMC FM stations
| Red solid light: momentary sync loss
| Green solid light: normal TMC traffic data flow. The GTM 10 must be in an area of service and be receiving adequate signals to display a solid green light. - Verify Signal Strength: If you are inside a building where radio signals cannot be received, you may need to take the vehicle outside for testing.
- Verify that you are in a service area: Check for service from the pay service or free services, if available.
- Check the Map: Turn on the GPS device and access a map. Check for traffic alerts and symbols on the map. It may be easiest to browse the map of a roadway or intersection under construction or that is known to have frequent traffic hazards. If possible, refer to the Owner’s Manual.
If the above tests fail, either you are not in a service area, the purchased subscription is not activated (see below), or the installation might be faulty.
Activating a Subscription
If the owner has marked Yes for 2b, you need to enter the 25-character code into the GPS device to activate the purchased subscription. As each GPS device operates differently, consult the Owner’s Manual for complete information about entering the code. After you enter the code to activate the subscription, you can use the steps listed above to test the installation.
step 6: Mount the GTM 10
If possible, place the GTM 10 where the LED can be seen without dismantling the dashboard.
- Mount the GTM 10 according to the owner’s response to question 3:
- Attach with foam tape: clean and dry a flat surface behind the dashboard. Remove the backing from the foam tape and attach the GTM 10 to the flat surface.
- Hang freely: bind up any slack cable from the mini-USB cable with a wire tie and let the GTM 10 hang freely behind the radio.
- Check that all cables and the GTM 10 are secure and free of obstruction.
- Replace all parts of the dashboard to their original locations.
- Repeat the testing as described in Step 5.
