is Google map navigation only available to selected country I love using Google map to give me direction. however, I would like it to provide "turn left, turn right" voice while I am driving. I heard Google map navigation able to provide such feature. I search from android market but cannot find one. is it only available to selected country? is there any workaround, or other software I can try out?
It's limited to specific locations, and only available with a data connection.  See this question on the location limitations and this question on alternatives.
