iPod AND sat radio

[clickman]

So I''m tired of the alternator whine, and want to install the recommended ground loop isolator.

But looking at the Radio Shack unit, it has RCA connectors and apparently a 1/8" jack adaptor. I can't figure out how to hook it into my circuit.

At the moment I have the power and ground connected from the iPod adaptor cable hooked into the spare phone harness at the bottom of the console.

Some ground loop isolators do hookup to the power cables, but most go in between your audio cables. The standard Becker hookup cable gives you two RCA plugs to hook your audio into. Plug the ground loop isolator into these RCA plugs, then plug the RCA to 3.5mm Y-cable in the other end. You want the isolator in between you radio and audio source, and if you have a cable with only a 3.5mm jack you will need some adapters.

Sorry for my ignorance, but I still don't know how to hook it in. I have the PIE 3-way cable (pic attached), not the Becker cable with RCAs.

One end goes into the back of the CDR220 and the other end goes into the iPod. Then there is the power and ground wires.

I attached both to the spare telephone harness: red/green for 12V+ always on and brown for ground. (I had also tried the ground wire on a screw in the console - no success.)

So I'm assuming I'm going to have to cut the RCA connectors off of the Radio Shack GLI and splice it in somewhere.

But where?

Thanks!

That cable is going to make it more difficult. Unless you want to replace the cable, the best solution would be to use a ground loop isolator that you can splice onto the power and ground wires. They are not very common, but I have seen them at PepBoys. Some isolators work better than others, so I am not sure how well this type will work.

Replace the cable with what?

You could replace it with something similar to what I have, which would allow you to plug the RCA isolator in.

Note the warning on this page, you need a different cable for newer iPods.

Thanks rick3000. I appreciate all of your responses.

Being the cheap SOB that I am, if the GLI between the Becker head unit and the iPod is the best way to go, I think I'll try stripping my adapter cable, isolating the audio inputs, then cutting off the GLI RCAs and splicing them together.

Wish me luck!
