I've just bought a nexus one. Have the unlocked version as I'm in india. The phone is awesome and everything else works fine. The web experience is amazing.
However,whenever I go to Google maps to use GPS to go around, after the route is calculated,I do not get any voice guidance. It shows me the route correctly and everything else is fine. But there's no voice. I googled it, and found out that voice guidance is there. I tried browsing through options and settings, no luck. There's nothing about voice guidance on maps mentioned.
