Add bluetooth to a Sony DSX-A210UI car player
EN
In that topic, I`ll show some small modification to a quite recent model Sony player.
Originally it have only Aux, USB, and radio functions. Pretty basic, but from other hand the amplifier is capable up to about 25W RMS constant output and 55W peak. Sound is quite clear, so why not adding Bluetooth instead AUX.
For that purpose I have to find where that AUX pin end up on the main PCB borad:
Then was added the BT module itself and small DC-DC converted to 5V that is rated up to 1A
So what`s the point of that DC converter?
Well, sure enough you can use 5V from the PCB and start the BT board via some transistor. I just choose to have separate power supply to my module and also that converter is connected to the 12V amplifier line. In that mode, when you start the player then it activate the Bluetooth itself.
Up until now, it work quite well I must say and the sound is not bad too.
If you wish, you can use that idea to build some on your own..
Good luck!
