Tested audio sounds great couldn’t get the iPod part to work on a classic so not sure if that part works but it does seem to hold a charge, I have included a 3.5mm - 3.5mm (AUX cable) that does work excellently. Might just be my iPod.

Remote has had batteries freshly replaced, it’s a little dinged up, as the previous battery was swollen (no corrosion) but the remote functions.
