Thanks for the reply.
I still get the ‘NO AUX’ message between tracks even when I don’t use the ground loop isolator. It’s hard to say if it’s better or the same.
What I mean by the auto-detect is that the stereo has a mode button that selects the different inputs (it’s just a stock stereo in a 2007 Caravan). Without anything plugged in, the mode button selects between AM and FM radio only. There are no other options until you insert something. If you insert a CD, then you can switch between AM, FM, and CD. And if you plug in something to the auxillary input, then one of the options will be AUX. There is no option to select AUX until you plug something in (and apparently, until there is a signal)…
