    Hissing/static on car stereo auxiliary connection with Nook Tablet

    This is a question about using my Nook Tablet through my car stereo's aux input. It's an off the shelf Nook with no modifications to the OS.

    That said, I discovered a possibly huge (for me) issue this morning when I connected it to my car stereo auxiliary input for the first time. There is a constant hissing/static sound coming from the Nook when playing audio. When I pause the music it goes away, but then comes right back as soon as I start playing again. It can also be heard anytime the Nook is playing other sounds such as the lock/unlock sound. It's very loud, at least as loud as the music, and changes slightly when I move the aux cable around but never goes away. The same aux cable was tested with other sources (mp3 players) and worked great and the static cannot be heard when listening to the Nook through headphones. I have not had the chance to test it on my other vehicle's stereo, but it is completely unusable in my car.

    Any ideas/suggestions? Is there some sort of shielding that may need to be done on the aux cable? If so, why would this happen on the Nook when it doesn't happen on anything else? Thanks in advance.

    No, it isn't being charged at the time.

    I read in another thread somewhere that it could be an issue with the noise being amplified by the car stereo's amp that isn't audible through earphones that have no such amp. Does that make any sense? If it does, any idea how I may be able to get around it?

    Thanks

    sounds like a possible ground loop isolation issue if it's plugged in while playing
