I have a 02 eldo with the bose option, and I would like to add blutooth to my stock stereo. I would like to keep the stock components but add blutooth to my stock stereo. Can anyone provide data regarding the bose head unit? I would like to remove or augment the tape player and install a blutooth receiver inside of the stock head unit. I would like the tape source to function as a blutooth adapter. I am experienced with electronics and any schematics would be helpful. I don't wish to use a antenna or tape adapters.
