Aloha Folks, The original stereo/cd radio unit in my truck works fine but I can't see the station numbers where searching or other instructions. Is this an easy fix, meaning changing out some light bulbs? Question: if it is just replacing some light bulbs, how do you take out the unit from the dash? Is there a special tool? Question #2: If this is not about the bulbs and it is an LCD panel that has gone out, do you recommend getting another stock unit, if not what brands work well with our truck's system? Thank you very much. Mahalo!
