Hi all, I am using HTC desire S from the last few weeks, its first impression was very good. After some days I found some problem while sing my Google navigation. I uses Google navigation a lot, because I love travelling and I travel a lot. I have some problem while using the Google navigation, I had noticed that while using the Google navigation the voice instruction come out from the phone speaker if I am using Bluetooth headset also. I had tried for it on the setting but no change, please help me out of this problem.
