How can I easily play external music in my SL I have an SL R230 BJ 2004 Unfortunately, there is no AUX in the glove compartment. (comfortably, there are some other SL`s) An FM transmitter works rather poorly than right. I heard instead of the CD changer you can plug in a Bluetooth adapter? Do you have tips? I think about changing the radio. However, I would like to keep the originality. Otherwise, I would like to give you other tips.
