Hi All, I have a 55 Plate A6 Avant with the 2G MMI High. Just purchased it and love it.

It diod not have factory phone prep so had the FISCON OEM unit fitted by Car Communications fitted and works perfectly with the Bluetooth connection from my IPhone. I currently have the software version C6-HU 6350 12.0.0 0513 which is quite outdated. Have spoken to the nice folks at Audi updates and been advised to get the three discs. Disc one 5150, Disc 2 Bluetooth and Disc 3 5570. I just want to check that if I run the Bluetooth upgrade it will not screw up the FISCON unit? Or should I play safe and only do disc 1 & 3?

Advice gratefully received:-). I hate to ask, I need a little help understanding this better before I commit. My version says SW: C6-HU 6350 05.0.0 0413 which suggest I think anyway I am using a very old FW. I have downloaded from Audi Resource (all available updates, as follows. To update my system to the most current, which of the below disks do I need to run in which order. I have read so many posts where some say I need to first update to 2120 before going further, others say start with disk 1 of the 5570, so to ensure I dont screw anything up, can anyone advise.

The MMI controls (to the rear of the gear lever) on a left-hand drive Audi Q7. 4L0 998 961, 5570 (55.7.0), Europe, (A6/A8/Q7) 3CD set (SVM-Code:.

Also, I understand there will be an issue with the instrument cluster, but I have no actual fact detail on what the issue will be, and if by instrument cluster they mean the small display between dash dials, and if they do does it mean it wont display anything at all or that some items wont display. Sorry I am a technical person (IT/IP/Web so see these things as logical, but so much different information makes it hard to plan.

So in a points style. Which disks in which order based on above FW verison 2. What issues should I expect to encounter during and after.

Your version 'C6-HU 6350 05.0.0 0413' indicates the following: C6-HU: You have an A6 HeadUnit [which is the ECU that runs the MMI software] aka Control Head or Interfacebox 6350: You have a HeadUnit without a video input [that is, you don't have a TV or Reversing Camera] 05.0.0: MMI version is 0500 0413: MMI software is dated 2004 Week 13 MMI update CDs contain two types of software: a) The updated version of the MMI that runs in the HeadUnit b) The latest firmware versions for ALL of the different types of MMI devices - amp, radio, CD, phone, etc. The MMI 5570 3CD set is actually: CD 1: MMI version 5150 [slightly later version than the 'Update 5150' CD that you list. MMI is the same but slightly later versions of device firmware] CD 2: Bluetooth phone firmware updates CD 3: MMI version 5570 [Year 2008 Week 35] MMI update CDs contain ALL of the previous updates so in theory you can go from 0500 to 5570 in one go.
