I have Garmin Nuvi 260w GPS and Have a similar problem I did and fallow all the direction from Steps 1 to 4 as stated above ,GPS started showing running Visual Maps directions ONLY . Great. better than nothing ?
But found Talking Direction is stop working , GPS DONT want to Speech ? . I checked GPS Volume, Sound Settings, i.e. sound is Abled or Disabled, it is abled and also Couple of time switching either way but GPS Don't Give Voice Direction. It Works and Gives Both Sound/Visual Directions together at the same time before performing Fix steps 1 to 4. That means when working all alone on GPS battery and not connected to Car at all> Please advice if you good guys have any solution ?. Abee
