Bluetooth board

[hawkeyefxr]

Hi all, new here and electronics to me is a bit like speaking Japanese with an Irish accent.

I dare say this has been done to death somewhere hear but here goes. I have a 70 year old radio that i want to put bluetooth into. Can someone suggest a good board to use,i would like it to be stereo around 50w per channel with a 5 or 12 volt dc supply.

I have already bought a bluetooth board and connected it up, my phone saw the board but would not pair. There wasa power light and a bluetooth light which lit up when power was supplied, the only thing is the speakers would make the burping noise at about 2 second intervals.

All wiring was correct, both board and phone are Bluetooth 4.0
