Help with amplifier needed

[Peter Podi]

I have purchased 2008 Audi a6 c6 avant with no sound at all.  MMI works, navi works, radio list frequencies however I cannot here anything.  I have opened the left compartment at the back and the amplifier is missing, the optical loop is bypassed with a connector. 

Where can I find a correct amp part number for my car?

You'll need to go into Audi or type your reg on a parts store online to find the correct part number. As it'll depend if it's Bose, or standard Audi one etc. 

If you've just bought it from a dealer in the last 30 days then it's their responsibility to fix it free of charge as you're entitled to a full refund in the first 30 days after sale

Private purchase, no joy. 

How to tell if my system is Bose or standard Audi? would these use different connector?

Picture of a connector if you can tell?

Bose would be listed in that list, also Bose labels will be on the speakers. 

[Peter Podi]

Thank you. 

No Bose labels anywhere.  Non-Bose system then.  

According to various sources: standard amp is available with following part numbers:

• 4F0910223H
• 4F0910223K
• 4F0910223L
• 4F0910223M

Can anyone advise if any amp above can be connected to MMI system?

What is the difference between these?
