Sony CMT-LX20i upgraded with Sony SS-H771 speakers and a bluetooth receiver. Receiver attaches to the 30-pin Apple i-device port on the stereo: works great. You can also remove the receiver and dock (and charge) your (older) Apple device. Unit can also play CDs (remember those?) and AM/FM radio, although I no longer have the antenna. Great sounding and very capable stereo package. Includes all cables, the remote control. and dock adapters for different models of Apple i-devices (not pictured).
