Harmon Kardon System
Hi All,
I hope someone of you can help with a non functioning Harmon Kardon system in my 2004 Rover 75 C0ntempoary Tourer. Having been advised that water ingression to the tuner in the bootwell was responsible I replaced it along with the head unit. Unfortunately this didn't have the desired result and all that changed was a blue background light appeared on the head unit. I have disconnected the TV unit along with the Sat Nav as they are no currently obsolete. Not alone am I having radio problems but the car has adopted a mind of its own in the sense that the windscreen wipers are liable to start working even when the car is parked up. I would greatly appreciate any help as I absolutely love the Rover 75 experience |

I'm afraid that you cannot do that Michael if you want the audio system to work. You will need to reconnect them. I would also advise refitting your original radio module (tuner) and head unit (known as the Bordmonitor) then tell us, in as much detail as possible, what happens when you try to use the radio.
On the face of it is sounds as if you might have a problem with one of the multiplex busses. Simon

Wipers going nuts is quite likely a frayed through cable inside the nearside wing - there's a (I think) red and green cable which runs in the loom and is the switched earth feed from the BCU - if that frays through an touches bodywork then the wipers will run - as a short term fix you can remove relay 1 from the under bonnet fusebox as that's the one that feeds the slow speeds on the wipers, and they can't run without that.
To check the wiring loom itself, you're looking at taking the passenger front wheel off, removing the plastic inner wheelarch cover and then the loom will be the bundle of 50-60 cables just on your left as you're looking inwards - it's probably frayed on the bit of the chassis that it passes over in there - if you find the bit that's frayed you can wrap it with electrical tape and then move the entire loom a little to stop it fraying again. |

Before anyone jumps to conclusions about wiper behaviour, transposed switched and permanent live wiring in aftermarket head units and redundant K-Bus wiring causes just such faults
In terms of the HK setup, I was led to believe that the amplifier is completely separate to the original radio so can be used as a standalone system with whichever head unit your desire. Mind you wireless are not my forte, as long as you can get Radio 2, I don't mind what is fitted Brian |

If anyone knows the input arrangements of the HK amplifier intimately and knows otherwise, I'm all ears. Simon
