I have a 2003' car which has CD player without any AUX input. CD player has problems with playing CD-RW and even CD-R and it supports CDDA only, no MP3. Also, I have a mobile with Windows Phone 8.1.
Now I have that idea of purchasing a BT & FM transmitter, so I could stream my music collection from fb2k on phone via BT and then via FM to the car radio. Is that possible? BT stream from fb2k mobile to the transmitter is what bothers me most.
