I have a '98 GS400 with 156,000 miles in very good condition. Last night I noticed that the radio display backlighting (light green) is out on the left side. How do I replace any bulbs in this?

I don't think you can... I'm not saying its impossible but I hope your familiar with electronics before you take apart your radio and attempt to.

If you have a Lexus radio instead of a Nakamichi, the radio is made by Pioneer and the display on the radio is a problem. I replaced the display on my own radio. It's a 2000 GS300. I ordered it from Pioneer. http://parts.pioneerelectronics.com/part.a...ductNum=CWM4931 And the instructions for radio removal are at http://www.carstereohelp.com/stereoremovalLexusGS400str.htm
