I have the same problem with one radio Becker Grand Prix 754.Is there any way to unlock it?
Thanks in advance.
Hello. So somebody find way how reset this radio?
How to solve this problem ?
Have the same problem.
For me the DIP8 with the designation PCF8571P is installed.
Does the dump have to be programmed here?
Thanks for your help (;-)
PCF8571P is EPROM and not EPROM!
She must be energized all the time.
For this, there is a battery inside the radio.
When the battery is discharged, the dump in the PCF8571P is erased by itself.
Need a dump from the working radio
Read without disconnecting the battery .
In the non-working radio, replace the battery.
To contacts 4 and 8 PCF8571P be solder battery 3.3V.
To the 4, 5 and 6 buses, connect the GND, SDA. and SCL from programmer
Programing PCF8571P read with the working radio dump.
Do not solder the battery to disconnect the programmer wires from the PCF8571P.
Also, without soldering the batteries, the PCF8571P should be soldered in the radio and only then it can be repaired
I am sorry ( google translator )
Many thanks for the quick answer.
Now I need the program of a working device.
The dump up does not work.
I am sorry too (google translate) (;-)
does anyone have a working dump?
