Hi There,
I'm *STRUGGLING* with my MMI as per
http://forum.a8parts.co.uk/showthread.php?t=16341
I thought it was the gateway, coding or some such, but it has taken me down QUITE a rabbit hole.
I just ordered up one from ebay for about £50, which is
HW - 4E0035729A - You have 400 at the front 4E0 is typically the d3 audi.
SW - 4E0 910 732
Looking at reversing camera retrofits they are quite often swapped out for the A model, which has a green FBAS connector on it - Mine was already an A
Mine had SW 4E0 910 730
However a lot on ebay are A6's with 4F0 software but the same model number. How convertible they are i'm not sure.
I *MAY* hit component protection which is a dealer job or trying to copy a chip across - The programmer is cheap, so i've one on order

I'd also add i'm VERY new to this MMI journey and i've read a lot, my head is spinning a bit, so please check stuff first to verify for yourself!
