I'm sure the inductive charging mat would work fine, I'd just rather not go that route yet since it makes the phone bulkier (and it's a good chunk of change). I was referring to the fact that the charging and audio cables were run next to each other for 3ft which could induce voltage from one to the other. I f that was the problem, a ferrite core could help. But, if that were truly the issue, then every ipod should have the same issue since running charge and audio in a cable is standard practice for them. I am doing that with the ZVM, but it's only a 6" run.
