Newbe A3 Upgrade mfsw Retrofit advice please.

[A3newbe]

I have a 2009 A3 convertible and am looking to add cruise control and a mfsw and Android head unit with reversing camera.
The current steering module is a 1K0 953 549 AH, does this mean i need a 8P0 953 549 F? (I have also read somewhere that a 8P0 953 549 E is compatible?)
Or depending on when in 2009 the car was produced could i need a 8P0 953 549 K?
Will i need a new airbag cable
I am also not 100% about which steering wheel to buy i dont/wont have the factory bluetooth module and am going to be using it with an aftermarket android head unit with canbus and compatible with steering wheel controls.
Can i fit any style A3 8p mfsw? ie 8P0419091DTWUL , and will the telephone functions control from the wheel work?
Any advice greatly received.

Hi Thanks, i had and have been googling i know for sure the 8P0 953 549 F will work on Pre 2009 models and the 8P0 953 549 K on post 2009. Just not 100% on my year 2009, i think i need "8P0 953 549 F" but am not 100% sure. As the modules are not cheap dont want to add it to my list of useless parts, (Complete engine,DMF and turbo so far)
