I bought a brand new iPod shuffle blue aluminum, current generation.
I swapped out the 2nd generation iPod shuffle in my car for the new iPod shuffle.
Sometimes, when I play music from my current iPod shuffle, the music (actually the signal/waveform itself) just becomes suddenly quiet, like it fades...for a second...and then it comes back full volume. Or, sometimes, it'll fade, then completely turn off. I have to turn it back on manually. This usually tends to happen more in cold weather or when I open the car window.
My old iPod shuffle never had this problem and I had that in my car down to -20 degrees with zero issues (except for 1-2 hour podcasts) in 4 years. And I haven't changed any of the wiring, so the new iPod shuffle shouldn't be affected by my car connection.
What's going on????
