Going back to San Diego from Atlanta tomorrow and thought I'd give this a try. Saw the expected route (I-20 to Dallas, I-35 to OKC, I-40 to Flagstaff, then to Phoenix and San Diego before changing any settings. Noticed the default was S85 and tried both S60 and NEW S60 and both showed a route deviating at Tucumcari, NM to Denver and I-70 for an additional ~20hours. Nothing in the other settings seems to get it back to what I believe is the correct route (the first one).
