I've been interested in adding a hard-wired auxiliary input to my 97 bull for a while. Lately a cheap $20 bluetooth radio transmitter has done the job, but there are a few problems I have had with it. I've done some reading and I found a good write-up here. However, it says that "the cassette or CD player needs to be functional for this mod to work." The problem is, my car doesn't have a disc changer anymore, but my radio is equipped for it. I want to replace the CD functionality all together, since I can't use CDs anyway, but this write-up seems to suggest I can't do that. I was hoping to preserve the cassette player functionality, as it works and I want the option to use it. Is there any way to perhaps "trick" the radio into thinking a CD is playing for this mod to work, or is this just a pipe dream? If this is a dumb question I'm sorry, I'm a high school student trying to make the best out of his first car. I would prefer not to have to install a new DIN radio and ICP panel to have this functionality.
