NO TURN-by-TURN VOICE guidance voice (SYNC 3 NAVIGATION) after start of navigation. At start of route "preamble speech" is OK and volume adjustable using knob while she's speaking per usual ... but NO voice turn-by-turn guidance after that. Worked fine until I hit 30K miles or so. Did I shut down turn-by-turn voice off by doing something in settings? Is it "off-to-see-the-dealer" time? Thanks for any clues.
