Well! You've certainly gone a lot deeper then anyone else I've seen on the forum. I may have to learn SMD soldering yet.

First off, if I'm interpreting the pictures properly, you've kept your OEM buttons with the new radio. I don't think that will work.

How does the buttons connect to the radio? Is it direct or though the car's harness? If though the stock harness, that could be a problem. Any chance the connection is done backwards? I do think the connection is the most likely source of the problem - unless you're running into issues somewhere else.

EEPROM. Did you look up the function of the broken pin? That could certainly be an issue. But I'd expect far bigger problems then this if it was a address or data line.

Another concern is that in the dealer in trying to help you might have flashed the wrong software into the radio. I'm not sure as all dealers know how to work to the system for "user installed upgrades". By default it's probably going to ask for the car's VIN and then the software will deal with the car as if it unchanged.

But for now, I'd go with the theory of wrong buttons or connection harness. But that could change if you find functions missing, etc.

yub, I am using my existing OEM buttons cause it is have folders navigation buttons. Also I tried the other 95914367, but they are both acting the same way.
What happens if you try the 94563276?


it is 24c128
OK, the broken pin is a chip-level address, a device select. The fact you got anything out suggests it's not an issue. You could probably put it back in if you suspect your dump and burn to be an issue. Unless there's other EPROMs or selectable devices, I think you'll find the pin was just grounded.
