Sony CDX-M800 Code Help .!:

Yes, you've made some nice photos but the one that would
have interested me the most, is photo of the bottom casing.

Is there an opening - with solder links? I've managed to
remove codes through soldering links, but I can't remember
if this applys to your model of Sony.

Ignore previous post, you have supplied photo
of bottom casing - not the radio I thought
it might be.
Sorry

Hi, this radio can be done without stripping down just cut the 7th to 11th slit on the bottom lid, where you see the tuner pins, so that you can solder on to the end two pins which are SCL & SDA also put ground to case, power set for 10 seconds before you do a read, then switch power off then read code. Job done in approx 5 mins.
