soooooo... the oem replacement stereo i ordered from like china or korea or something didn't come with the code. am i seriously out of luck? is there no way to figure it out or what?

 

Their is a hack for the code do a search, if it doesnt work im selling mine for 20, 50 if you need the disk changer too.

 

There's no hack, only thing you can do is take the thing apart and read the EEPROM. You also won't get a code from Audi unless you have the VIN of the original car it was installed in and possibly proof of ownership of said car. I'd be able to do it, but I'm on the boring side of the border.

 

first off dont answer questions you dont know the answer too, because there is absolutely a hack for it.

for example, i bought an a4 a few years back and it didnt have a radio code took it too a local tuner they HACKED it so that you never need to put a code in ever again.

 

and everything is HACKABLE

 

i am interested, and i PM'd you.

 

Was it a symphony? I've read about a method that basically disables the canbus id check, which prevents the code prompt from ever coming up. I assume that's done in the EEPROM, which can't be assessed through the k-line or canbus as far as I know, meaning you have to take it apart to get to the physical chip. Maybe something like that exists for the concert too, but it still stands that you need to get to the EEPROM.

By hack I was thinking more along the lines of a hardware method outside of the radio itself. It doesn't really matter what you do after you get to the EEPROM, it's getting there that takes time and costs money. Both the method I mentioned and this hack take the same amount of time, only difference being the end result.

 

Hope you didn't spend more than $40 for your radio with out a code...
