Ground loop isolator

[Stache]

I feed my iPhone into the aux port (cassette deck). I plug my phone in to charge while playing and I get a loud annoying buzz. Research tells me I need a ground loop isolator on the 3.5mm connection.

 

I use the Sena SM10 to link the onboard stereo to my Sena SMH headsets (rider and passenger) If I plug the sm10 in to charge while playing, same noise.

 

I hope somebody has hit this before and can recommend a make/model of isolator.

This one from MCM would be the easiest way to go.
