Becker Mexico 1420 code issues

[DaniTD]

Hello,

I'm trying to get the code for my old Becker Mexico. I tried to get help from other people to recover the code using the serial number, also tried calculators but the code is not working.
I then got to dump the EEPROM where supposedly activation is. The dump seems ok, tried to use some tools to get the code but also, I can't get it working.
Can you help me, please? From what I see, this kind of EEPROM was used in 837/1400/1401 models also.

Thank you very much

Hi, thanks! I already tried that code but the radio doesn't accept it :blue:

hi try code 9710

Also tried that one... no success. Seems that this EEPROM is a bit different from other Becker's...

[DaniTD]

Also not working... seems that I'm getting out of luck :blue::smilet-digitalpoint

Try 9701

[DaniTD]

Can you post all the numbers from your eeprom?

wbr

What do you mean by all the numbers?

[shooting]

Nothing... It doesn't work

I mean what is physically written on the chip, also try 9701

9701 didn't work.
Chip is a BAW574252.

Read dump 24c01............

Hi if code not work post stiker with serial number!

[DaniTD]

The BAW574252 is the 24C02 compatible chip that this radio uses, I can't see another IC with this purpose...

[DaniTD]

Serial is BE1420A6455075, but the codes I got from that don't work... The serial is the same as the one read from the EEPROM.

Code from serial number is 9439 maybe you need to try code in car!

I already tried that code on the radio yesterday with no luck :(

Hi, try code 1685

That works!!!!! Thank you very much! May I ask how did you get it?
