Most of you understand your LR4s much better than I do but for those of you who didn't know, the TMS data (at least in the 2014) is provided by a free service and comes through FM radio. Why do I care?
For the past 2-3 weeks I haven't been getting any data. The TMS symbol at the top of the Navigation screen would always show a red line through it indicating no data available. Even when I set routes on major interstates where I knew there were issues.
So I wrongly assumed this had something to do with a change in my Sirius Sat service thinking the data came from there. In fact, when I called my dealer's service department the first answer I got was that the data came from satellite. (Which of course led to an even more confusing conversation with the Sirius folks about why I was no longer getting my traffic data.)
I eventually went down to the dealership/service department and started asking around. Finally we found someone who knew that the although you can order traffic and weather service from Sirius that is not what the Nav system uses. It uses a free service that sends signals via FM.
That still didn't explain to me why I had stopped receiving data. But, realizing that I had not used the FM radio for over a month I decided to see if using an FM station would re-initialize the TMS data signal. Within 5 minutes after turning to an FM station data was coming in again. I still don't know why it stopped. Maybe not using it for a long period of time. Or maybe something they did when the performed a multipoint inspection a couple weeks ago. In any case, it appears to be working now - and not only when I am listening to FM.
If you notice that you are not getting TMS data you may want to switch to an FM channel for a few minutes and see if it comes back
