Hi guye I have a 2004 BMW 330Ci. The radio does not have bluetooth and I want to listen to my music from my iPhone. I believe I could have a mini jack cable connected some how but here they are charging me about $200 to install it. What other options do you know? Like a transmitter that allows me to select a radio station or something. I do not want to replace the original stereo but let me know what you know that is out there that works. Thank you.
