I installed one of these to my IS250, nealty plugged in under armrest and the round Bluetooth receiver sat at end of arm rest near cup holder so no wires showing. I then have my ipod to the right of steering wheel on a magnetic holder. Stick it on Aux and bang!, it automatically connects to the ipod, doesnt affect my phone which is connected to the bluetooth on car either.
Sounds amazing, no loss in quality with thousands of tunes all in 1 small device and no more messing with cd's.
Best money ive spent!!
