Audi concert 2 code - GSM-Forum

gyuszko · 03-04-2012, 20:07

Hi,

First, i'm not begging for free code, I have been in gsm for at least 10 years, now changed job, just wanna get some info about the thread title.
I have a concert 2 ( Grundig) in my a6 , just bought some aux adapter for the head unit to connect my iPhone. This is a cd changer emulator and has an iso8 mini jacket on the head unit side. If I connect it the head unit asks for code (SAFE) on the lcd, if reconnect original cable , head unit works again without code.
The problem is I didn't get the code from the guy I bought the car few years ago. What possibilities I have?
- Ask local Audi dealer for code based on chassis no. and radio serial?
- Somehow get code from radio serial?
- read eeprom dump and get code from that? ( I have ponyprog and enough skills to do that - unlocked e.g. many alcatel hd's and he's in many-many years ago with eeprom reprogramming

To tell the truth I don't prefer too much disassembling that cra.p. and desoldering chip from it

Thx 4 your answers

Come on don't be lazy just read the EPROM and upload the dump for code as I can give you code from dump but not with serial. May be some other member with calculator may give you the code.But serial number will be required.

Have the feeling your radio doesn't need a code, which is strange because your model of radio should be requesting a code when connected to the original harness. (after full disconnection from power?)

Given that the radio is not requesting a code when connected to the original cable, I would think that your adapter/crossover cable is missing connections.... I'd check that everything that should be connected when attached is being connected.

Thx 4 your answers, I've been tought about some missing pins too (original cable has all parts of upper connector - C1,C2,C3 - connected, aux adapter ( cdc emu ) has only C3 pins) I will test and post result

Mod. : yeah, think C2 has CAN bus pins too...that's must be missing when the cdchanger emulator is connected

Success

cut original 20 pin connector not used side ( CDC data, aux, where cdc emu iso8 is connected ) and connected original connectors line out lr lf rr rf and canbus , plus iso8 of cdc emu with cdc aux and cdc data lines. Now headunit plays music from my iPhone

and doesn't asks for code.
