The travel information comes from SiriusXM, so you need a subscription for it to work. I believe you can just subscribe to traffic, and not take the radio stations.
I tried it when I bought the car, but was not satisfied with it. Too too long to initialize (some days I was half way home - 10 minutes), and I never saw it update during my 30 minute commute. Since my commute is so short, I can either look at our state transportation web site before I leave work, or use the app they offer, and have the most up to date info. I bought a Garmin for use when I have a rental when I travel, and it has traffic, so if I ever take a major road trip I'll just use it.
