TMC is the abbreviation for Traffic Message Channel. TMC is traffic information which is transmitted by many transmitters along with radio programs. The TMC information cannot be heard in the radio signal, but can be decoded with suitable receivers. The information can then be used by the automatic route planner for instance to avoid routes with congestion or hazards.
TMC is built in through the radio system, which can be found on models such as:
- K 1600 GT/GTL
-K 1600 B
-R 1200 RT
Garmin Smart Link app can be paired with navigator to provide live traffic information at a small subscription fee. Find at your mobile app store.
