2005 CLS 500
No Radio Reception after replacing factory HU
I have a 2005 CLS 500 W219 and had the factory HU replaced for one of these updated Android BT enabled systems a little over a year ago. Since the swap, I have not had any radio reception. I have pulled the unit out several times and double and triple checked the connections behind the unit, and have never found anything to indicate a poor connection. It’s is as though the antenna cable is not even plugged in, but it is.
I have read on the forums that it is possibly due to the antenna amplifier not receiving power. I have checked all the fuses in the trunk and all are present and none are blown.
If it is true that all I need to do is supply a switched 12V to this amplifier, then I will do that, but I have been unable to determine which wire I need to supply this too.
Has anyone had this issue with their W219 and if so, I would greatly appreciate if someone could steer me in the right direction so I can finally have radio.
The original HU was the Harmon Kardon system with fibre feeds to the factory Sub/amp.
Thanks in advance.
