I own a FT-8900R. This radio is great. I have the face mounted above the car stereo in the dash. I had a problem seeing what position the volume and squelch knobs are at. I have my speaker in the headrest of my seat and tend to turn the knob up to far and startle myself.
Solution: I painted the indicators on the knobs with some acrylic craft paint. I used blaze orange for the volume and bright green for the squelch. Problem solved. I intend on adding some "glow in the dark" paint on the knobs in the future for increased visibility at night.
