I have found the correct chip thanks to your help guys, but I can not readout any information from it? I have the stereo connected and powered on but no information is coming when reading the chip. Please see attached pictures, am I doing this correctly? First time trying to make this work. Thank you for your patience...

Trying reading your chip out of circuit, but if not

I think you maybe trying to read the wrong chip,

take the circuit board out of the chassis (Frame)

look on the underside for the chip mentioned above (locate Memory FM24v01 (24c128) and read)

You must remove chip from the board. This model cannot read/write in circuit.

Thank your for your help! But just to be sure, do I understand you correctly that my programmer GQ4x4 does not support in circuit reading? Or is it the chip that is in this radio unit that is not possible to read in circuit? I was told GQ4 programmer was able to do in circuit reading.

Sorry for my basic knowledge, I am trying to learn from scratch.

Thank you for your help guys I managed to read out in cirucit after some more tries.

Can someone read out the pin code and how to enter pin when radio is blocked like mine?

Now is my next problem, the radio is locked due to many failed pin code attempts. I read somewhere that one can erase sectors 265 and 266 but dont really know where to start from here.

Thank you for your help guys.

Can not try the pin code because I cant get passed the text that the radio is locked.

[MrRepair]

It's not the programmer type that limits in circuit operation, but the circuit design itself.

Here is unlocked dump. DK masters have already supplied the correct code.
