Hey all, long time reader first time poster. The touch screen in my Prius recently broke. I'm replacing it with an el cheapo android double din. I've ordered the proper converter for the JBL amp but I've read I need to reset the eq and pump up the volume before I install the new unit. I can still control volume with the knob but is there any way to reset the eq. Although as I'm typing this I'm thinking duh, just unplug the battery for a bit. Will that work? How long do I need to leave it unplugged? Thanks!
