MMI questions
 

So I've got a 2010 A6 with MMI+ 3g. I've got two questions:

On my 2013 Honda Odyssey, there is a Gracenote database that links CDs to the tracks, so when you insert a CD it displays what the tracks names are instead of "TRACK 1", "TRACK 2" etc. I noticed that when I insert a CD in the Audi's CD driver, I get the name of the tracks. On my Honda, I can update this database via a download link from Honda. How is the Audi's database updated, if at all?

How big is the hard drive to store music in the Jukebox?

Mmi headunit !
 

I have 06 a6 mmi headunit not working, I find in the eBay many different. My SW 4f0910731B ,I find it some number but many different letter. Can I buy "SW 4f0910731" A or b or E...? Or is have to buy the letter B and what's the different between this letter.
Thank you!

If your part number is "4F0910731B" you should able to replace it with a 4F0910731B, 4f0910731C, 4F0910731D, etc.

The letter at the end is the revision level - E is newer than B which is newer than A. Usually you can move to higher revisions without a problem, as they are backwardly compatible. But you can't go to a previous version (i.e., B to A).

Thank you
My advanced key not working and the push to start ,when I push the button is saying no key identified ,this problem could be happened from the interface box? Or different problem?

you really need to run a VCDS scan to figure out the logs which are produced. Also, you may need to run individual scans on the MOST loop which your MMI leverages. Your issues all could be connected or separate, but without data it's all guess work on our end.

Replace your remote battery with a new one. But make sure your near your car. When you replaced the battery the remote will be looking for your car. There will be a red light on your remote that will flash until it's linked to your car. At this point push the lock unlock on the remote. Now you shouldn't see that message. This happened to me last night. I changed the battery and the message went away.

I did ,my message went away, but still have the doors doesn't open with out pushing the remote control and the start button still not works.Now the stop engine button is works.

Are you pushing the brake in when you push the start button? For the doors not opening with out remote try holding your fingers a little long under the door handle. I know on mine I have to wait 2 sec sometimes.

Yes I pushing the brake,
Today I did change the interface box now is everything works, but I don't have a sound the mute icon is there.Nav is works, I try to do pushing one time the on/off switch still nothing.
