Need to install ground loop isolator between REX3 and Head unit

I have a hum in the speakers on my Territory when playing a DVD through the AUX input and the head unit and have been told that a ground loop isolator might help so i bought one from JB hi-fi and hope to install it myself.

The isolator has RCA leads and I hope to find that the audio input at the back of the head unit is also RCA connections - does anyone know if it is? Then I can just put the isolator in line hopefully.

Also I was looking at how to get to the back of the head unit and it doesn't look easy - anyone have any tips on this also??

Re: Need to install ground loop isolator between REX3 and Head unit

You will have to drop your hood lining to install the isolator on the rex.
The cables run down the right side A pillar but you will only find rca connectors up at the unit.
But i seriously dont understand why you are having noise troubles in a rex system.
I have installed heaps of them and i have never had that problem.
I would check all the connections before i started adding third party components to a rex .They really are a high quality system.
Hope this helps you.

Thanks subz3r0 I installed the gli in the head lining but it made no difference as you suggested. When I spoke to Ford they said it is normal to have a hum and there is nothing that can be done - I don't believe them though...

Re: Need to install ground loop isolator between REX3 and Head unit

Heres something you could try.
The way ford has designed the power connection for the rex 3 is .
They plug it into the blue plug behind the drivers fuse box.ie: audio connector.
My suggestion is this.
Unplug this connector and hard wire these connections.
Sometimes something as silly as a bad power or earth connection can create problems.
I must admit i am a bit sceptical of how thin those wires are on the audio connector every time i install one of those rex systems.
