Greetings from Mississauga! :>)
With all Bluetooth devices you have to press a button on the device to send out a signal to the Phone whilst it searches. I wrote this tip on connecting.
Pairing Bluetooth Devices
Posters often ask "How do I pair my Bluetooth ???" Insert whatever device you have at the question marks.
Generally, you need to read the instructions for the camera, headset, speakers or whatever the Bluetooth device is.
Roughly speaking though.
Settings - Bluetooth - Search, on the Android, iPhone, Windows phone whatever.
With camera, speaker, headphones or whatever the Bluetooth device is, you have to press a button on that device to send out the signal. On my Bowers and Wilkins T6 Speakers, there is a button on the top with the Bluetooth symbol on it. This is the part people usually don't do and ask for advice, thinking it will do this automatically.
When the Android device recognises it, click Pair, and if it asks for a code, the Default is '0000', (four zeros, no quotes).
