Okay, so, a while ago the am/fm radio module packed in on my IS200 sport standard stereo. I bought an 'err3' unit off of ebay (mines the older, lower CD slot version, this was the newer upper CD slot type). I pulled the 'err3' unit apart at work (overtime baby :D), found the tuner module, which had the same part numbers on as the one in mine. Bingo. I pulled mine apart (easier than the newer one as the CD unit doesn't need disturbing, just unplugging). Winner! New tuner module fit, stereo back together. I'm doing well today :D. Took it out to the car, plugged it in, success! Radio works :D. CD player doesn't. DAM DAM DAM DAM DAM!!! shows 'err3' oh sh.....
so, now I know how to diassemble and reassemble the dreaded lexus stereos, It would appear I also know how to break the CD units. What to try next........more ebay hunting maybe..........
at least I can listen to Chris Moyles in the mornings again! haha!
