I've got an audiolink that i bought about 2 years ago. Recently, I've been having problem where the ipod adapter isn't showing up to the head unit (pushing CD twice doesn't show the EX). I've checked if anything is lose (it's not) and I've found the only way to fix it is to unplug the car battery and then reconnect it. It then always shows up immediately and works for a few days until it doesn't show up again.

Any thoughts on what could be wrong?
