Greetings. Hw2. 7.5.28. This is the FW version on car delivery 2 weeks ago. Have been enjoying TACC. Freeways, and local roads. A couple days ago we got "Cruise not Avalable" when attempting to engage. And indeed, no greyed out speed setting visible. This seems a permanent state. No TACC for multiple trips now. Thoughts? Could dirt do this? It's fairly dirty. On other hand, last week while in a big downpour with lots of flying mist I got some message about radar not getting signal. It cleared up in minutes and all was well. I suppose that's different than dirt though. Thanks. Will wash and report back later today.
