Step 4: Route the Mini-USB Cable
Route the mini-USB cable from behind the radio on the
passenger's side of the vehicle. 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.
Step 5: Test the GTM 10
Observe the LED: Service reception is indicated
by the Green solid light, which may take up to five
minutes to appear for initial data acquisition.
Yellow dot-dash flashes: determining
which country you are currently in.
Yellow solid light: searching table for
active entry or scanning for new TMC FM stations
Red solid light: momentary sync loss.
Green solid light: normal traffic data.
Verify Signal Strength: If you are inside a garage
where radio signals cannot be received, you may need
to take the vehicle outside.
Verify that you are in a service area: Check for
service from the pay service or free services.
GTM 10 Owner's Manual
™
Check the Map: Check the map on the GPS device for
traffic alerts. Refer to the owner's manual.
If these tests fail, either you are not in a service area,
the purchased subscription needs to be activated, or the
installation might be faulty.
Step 6: Mount the GTM 10
If possible, mount the GTM 10 so you can see the LED.
1. Mount the GTM 10 in one of the following ways:
• 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.
2. Check that all cables and the GTM 10 are secure
and not obstructed.
3. Replace all parts of the dashboard to their original
locations.
4. Repeat the testing as described in Step 5.
