Merci beaucoup
English is an international langage, for me, all people should know talking in English. My English is not perfect, I see today that I should have listened more at school.
You obviously listened enough to make yourself understood here
Thanks
theres been a couple of Posts lately where NCDC's have lost their coding or pairing after being disconnected from the battery for a while, which was one of the reasons I thought about yours losing its config settings.
I didn't found those posts when I've launched the "search", you remember where are thoses posts ?
In a word, no, seem to remember Albitz had an issue recently with it not working after not seeing 12V for a while, but fairly sure that was a code (pairing) issue, which I dont think id the same problem as you have.
Reading the eeprom post that pscocoa posted up, Im guessing the 24LC16 EEPROM is used for storing the Radio Memory List, could be that this problem is hanging the Tuner Mode side of things and stopping the Audio switching to CD Player playing and Nav sound (Guessing!), or the Tuner board could be faulty?
Shame your overseas, as dare say someone with a Tech 2 and knows what there doing could read any issues with the Unit and investigate more.
What happens when you push the BC button, do you still get all the Computer Info on the display?, if so this should rule out any Pairing Issues with the display?
Think if it was me, I would be tempted to remove fuses feeding the HU or better still remove the ISO Plug from behind it for a few hours or overnight, and see what happens, you never know, otherwise looks like a eeprom repair job.
Thank you very much for your help. When I've changed the battery, there wasn't 12V for 3 minutes about. When I've started the engine, the Tunner was Ok (Nrj, Fun Radio etc..) only no sound. I've pressed "AS" button 10 sec and it has reboot. I'm sure, I've done a reset, lights of the station went out and then re-light.
I've seen in the manual, I have to put a 85Ah battery, but I put a 77Ah because all 85Ah are too long. I made a mistake ? Does it could be the cause ?
Tomorow, I'll take some pictures to show you. I've already contacted Opel and I'm waiting them to give me the solution.
The BC button is Ok, Computer Info is correct.
I think that EEprom is KO.

Florian's blog explains that EEprom doesn't like battery change without removing fuse before. It explain why it's written 0kHz instead of station radio. I' don't understand why this problem hasn't happened to others, you have all of you changed, one time, your battery ? And no one has gotten this problem...
I think, I will buy the new EEprom and change it, I will do a post for forum. Thanks again for your help
