iPod AND sat radio

[clickman]

So back to the cable I asked about in the OP. Anyone used that with succcess?

You will only get alternator whine if the AUX cable is hooked up to a power source. There is no way to completely eliminate it, but you can make it unnoticable at normaly volumes. I used a radio shack ground loop isolator (I found that the ones from Walmart where not as good), and it solved the problem.

My car has the AUX in adaptor from Becker and a Monster Cable RCA to 1/8" cable to attach my Ipod :

There is no power supplied to the Ipod, and no alternator whine.

When I used this same setup to connect my satellite radio, I did experience whine since the receiver is powered through the cigarette lighter.

I have since had the satellite radio permantly installed, and Tweeter told me they did install a ground loop isolator to stop the whine.

So clickman, I would get the parts mentioned above rather than the parts linked in your original post. You will not be able to power your Ipod, but you won't have any whine either.

If you need power as well, I would look into using a ground loop isolator with the PIE connection.

Hope this helps...

I hooked the ground from the ipod/sat radio connector cable (and from the aftermarket lighter socket that powers the sat radio) to a screw at the bottom of the console. I'm getting the alternator whine.

Rather than fussing with a ground loop isolator, why shouldn't I just hook those grounds directly into the main ground off the head unit. Why not?

You could ground it to the same ground as the radio, and while it may help, it probably won't get rid of the alternator whine. Your going to need an isolator is if you want to have a powered outlet.

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.
