    Need help on bluetooth batteries
    Hello
    At present I have a motorcycle contact system to connect to the cell phone via Bluetooth to be able to receive any phone calls while I am on the road. the first time i turn on Bluetooth and sync them with the system, first enter the code, here the unit needs to watch 4 zeros. From the ones I know a phone number can use 1234 just like their code? And this certainly will not work with my internal communication system.
    How do droids work?

    hope that i can understand
