Hi everyone.

Head unit powers up fine. Nav plus cd changer plus dvd all work fine and sound is great.
I just can't get any sound from the radio. I've tried a frequency tuner Bluetooth device what allows sound from a phone etc to play through a frequency on the radio. This works fine.

Just can't get any sound when tuning into any radio channels radio 1 2 smooth ....etc.

Any ideas?? 56 e320 CDI with Harman Kardon stereo.

Many thanks.

IIRC, the aerial is in the rear window heater and has an amplifier to give a signal to the radio. Worth checking the fuse for the amplifier and maybe loose / broken connection. Unfortunately I'm not sure where the amp is located. Is it a saloon or an estate?

Hi, sorry for the late reply.

It's an estate. Do you have a fuse number and location?

Many thanks.

If the fuse is okay, also check the connections to the rear screen. After that, the amps themselves are known to die. They're typically located behind the trim in the last nearside pillar next to the back window. Not sure about on an estate though. I suspect a similar location.

Thanks guys. Will look into it this weekend and report back......

If the amplifier is gone would this only effect the radio?
Cd plus dvd all give out great sound.

Many thanks.

Yes. because the radio is the only thing needing an external signal.

Yes there's at least one antenna amplifier usually below one of the rear side windows on an estate or below the rear windscreen on a saloon.

My R class has at least 3 of them and an RF filter!
