Updating MMI A7

[Ball02k]

Hi Guys

Keen to know how I can update the 3G MMI system without having to go to Audi (my local Audi are awful) and without having to spend a mental amount on maps update via 3rd party. I'm wanting a complete update with Nav update or atleast a bluetooth update (bluetooth keeps dropping in and out if the phone is in my pocket during music streaming). 

I tried to use the 2015 bluetooth update on the Audi website but it wouldn't work. 

Any help is appreciated, I've read other forums but they are either too complicated (and I'm not that stupid) or generally it's Americans or Mainland Europeans doing the update, looking for UK experience).

Thanks
