title: Use of GPS chipset
body: <p>I'm new to the world of GPS. Please help me understand the following:</p>
  
  <p>1) Why GPS chip is required? If the GPS antenna is enough to transmit and receive data, any normal processor could do the decoding of the received GPS data.</p>
  
  <p>2) Does NaviLink 6.0 has its own GPS stack? Doesn't Android has its own GPS stack?</p>
  
  <p>3) NaviLink 6.0 integrates A-GPS, Bluetooth 2.1, FM Tx/Rx on a single chip. Why do you require a chip for bluetooth for FM and Bluetooth? Is FM antenna not enough? Is a separate chip required for Bluetooth too?</p>
