How To Use TMC in Uconnect
The purpose of this thread is to provide a place for members to describe how TMC actually works in Uconnect. Members that use TMC a lot and experiment in congested areas will probably be able to contribute the most. My (this) post will cover what Ive found so far. For those that don't want to read this whole post
, here is a description from someone that uses it; BlckWK2 from Metro Detroit posted this on Jeep Forum in February 2015:
You can adjust how the traffic will be alerted/routed when an incident occurs. It is in the NAVIGATION MAIN MENU --> SETTINGS --> MAP GUIDANCE --> TMC ROUTE -->
Automatic: No black pop up window, reroutes automatically
By Delay Time: Setup specific delay time on main route. If set at 5 min, your route is rerouted if traffic issues cause more than a 5 min delay (automatically)
Manual: Black pop up window and lets user decide what to do
Off: No rerouting due to traffic incidents
I have a long commute to work and mainly highway through the Metro Detroit area. Lots of different traffic issues so I use my NAV a lot! I usually keep it on automatic. If you do this make sure you have the navigation guidance volume turned on. There were plenty times where I have the guidance volume off and totally don't see the new route if it automatically changed.

What is TMC?
Traffic Message Channel (TMC) is a technology for delivering traffic and travel information to motor vehicle drivers. It is digitally coded and carried via conventional FM radio broadcasts, transmitted on Digital Audio Broadcasting, or satellite radio. In the United States of America, XM Satellite Radio and Sirius Satellite Radio provide TMC service all over the US. Navteq provides traffic data to both providers. Sources of traffic information typically include police, traffic control centers, camera systems, traffic speed detectors, floating car data, winter driving reports and roadwork reports.
Each traffic incident is encoded and sent as a TMC message. Each message consists of an event code, location code, expected incident duration, affected extent and other details. The message contains a list of up to 2048 event phrases that can be translated by the receiver into the user's language. Some phrases describe individual situations such as a crash, while others cover combinations of events such as construction causing long delays.

Uconnect Help No Help
The Uconnect manual does not describe how TMC settings affect routing, other than what can be derived from the option names such as: Automatic, By Delay Time, Manual, and Off. Called Uconnect and they said to call Sirius XM. Called Sirius XM and they said to call Uconnect because all that SXM does is transmit the data provided by Navteq. Sent an email to Uconnect and in it also asked if there was a contact at Garmin I could communicate with since Garmin provides the navigation routing software used in Uconnect. Uconnect refused to provide any further information other than repeating to call SXM or talk to the dealer.
