2008 Santa Fe with Stereo/Nav unit. When I listen to XM satellite radio, I hear what sounds like an altenator whine/hum. It was disgnosed as such and my dealer replaced the altenator. No change. Now it's been almost 2 months and they keep telling me they cannot figure it out.
Looking for ideas to suggest to the dealer. I feel it's in the stereo unit, but nothing from the dealer. Ideas anyone????
Did you ever figure this out? I am having the same problem with a 2009 Santa Fe w/ XM/NAV.
I haven't taken it in yet though
Seems like this guy was having the same problem:
