I haven't made a DIY on the radio yet, but it should be done within the week. Do you see in the first pic that Creektrack posted? on the right where the a/c knob is located, there are 4 LEDs that go in a semi circle just above the knob? In the picture, they alternate between a green circle, white x, green circle, white x..
Well, I discovered, the LEDs share the hash marks. See pic... I wanted to keep the blue and red circle, but couldn't the way the board is designed. There are only 4 LEDs behind the knob, yet they light up 3 hash marks, 2 circles and a snowflake..
