Is it possible to use a old mobile as a bluetooth audio receiver?
I have seen several tutorials outlining use of old mobile as an mp3 player especially hook it up with an car audio player (via aux in port). I have a sony ericsson w700i walkman cell phone lying with me. I already am using it as an mp3 player in the car. I wanted to know if i can extend its use further and pair it with my new mobile to play music wireless. If it's possible it might well be used for making receiving calls via car audio too.
I know there are several cheap stereo bluetooth receivers out there which can be used for the same purpose but I am interested in knowing if an old mobile can be used for this purpose somehow or not.
