Google has launched a much awaited voice based GPS navigation feature in India. This feature is now available with live traffic updates in Bengaluru, Mumbai, New Delhi, Chennai, Pune and Hyderabad. Tough this feature is not available in offline mode as in case of Nokia Maps but can come quite handy. It is supported by all Android devices in India running Android 2.2+ and absolutely free. Better if you don’t like to pay for premium services like Map My India and Tom Tom.
