In navi unit down, is 2 flash memory inside !

You ned to read and post here you dumps !

In one of this flash is the code, check down !

Code and error counter are stored in navigation unit (lower part) in two flash memory

There are two case :

V1
2x 28F400 PSOP44 package
Code are stored in upper memory
Error counter are stored in lower memory

V2
2x 29F800 TSOP48 package
Code are stored in memory with "normal pinout"
Error counter are stored in memory with "reverse pinout"

What about this site radio-code.co.uk? They claim they can get me the code, is that so?

[Seby_TM]

You can try, but I think will not work !

I opened the Alfa 166 NAV today and I found 27c512 eeprom inside the casset player and 29F400 inside the nav.

Is this 29F400 the one I need to read or is there another flash on the other side of the PCI board?

[brchip]

Sure enough, there is another flash on the other side of the PCI board.

Which one should I read? lol

[brchip]

Nobody? Please help.

I read the AM29F400 flash on the botton of the board, and this is the dump. Could someone check if it's possible to get the code out of it?
