I have a few GARMIN GPS'S . When I went to the Drive 60 LMT series sort of a new learning curve ! Just picked up a Drive 51 LM, All is fine BUT I get no audio that says Recalculating when I miss a turn, It DOES recalculate fine, just no voice or ding when it reroutes like my other GPS'S do! I ave checked settings and find no way to turn on or off the voice notification for it! I am sure it is a simple fix but I am not real Tech Savy ,So please type slow with your reply lol Thanks for any help and Happy Holidays Rich
