Delphi GM Navigation 2005 radio

[eddiev1]

Hi all, am trying to figure out the eeprom chip on this radio. I believe it to be a 9375365 number on it.

Radio is Delphi 28006575,
'05 GMT257 tnr

Hi read 24c16 and post here

[eddiev1]

Figuring out how to use EEPROM reader, will post as possible

[eddiev1]

Let me know what you think, as see attached BIN file

[clusters]

Need the VIN of the vehicle that it is going into, they are VIN locked to the trucks.

Need to change the last 6 of the VIN @ 05ab-05b0 and possibly the letter at 05aa

[eddiev1]

Vin last numbers 256366.

Not sure about letter?

[Raimax]

Try these dumps and report
-TEST-

[eddiev1]

Thanks, will try both bins.

Curious why change 05b1 and 05b2, possible checksum?

[Raimax]

I guess. I do not have more dumps. Therefore, there is no possibility to compare

[eddiev1]

I have yet to try these dumps. It is quite cold here so want to wait till it warms a little. Chicago brrrrr

EDIT-- The bins work, all needed to do was change last 6 digits of VIN to current vehicle

[eddiev1]

So that wasn't too bad, I also did not have to change anything else besides the 6 Vin digits. The next step is to figure out how to set up the radio to automatically accept a vin.
Thanks all for input

I figured as much, have never had to change anything but the 6 digits, but on different radios.

Would really like to see a dump from a virgin radio myself.
