Hey guys, I just got a new Alpine 9886 and I am wondering what the three switches on the bottom of the HU are for. Each one of them has a label that says "Normal" in one position and "Ext AP" in the other position. The owners manual doesn't say anything about them, and I am curious as to whether these switches allow the 9886 to run active.
Thanks in advance for the help.
