The radio reception may be a little shorter range as discussed (AM is pretty weak, but FM works fine for my local stations). But the local sound (USB, CD, iPhone) is very good. I would say that it is better than OEM in my opinion. (I have no measurement data to prove it, but it more than meets my needs)

You can't beat this thing for the price to feature ratio. No its not perfect, but neither is any other $100 receiver out there.

Bluetooth works perfectly for phone calls. Song quality bit rate is better over the cable versus Bluetooth streaming, so go direct when playing from iPod/ phone.
