Newbie with E93 needs Tech help.

[charge]

My first post on this forum so be gentle!
Just down sized from A6 estate to e93 as the kids are out of push chairs and I was getting fed up driving a barge.
Not a total virgin to Beemers as I had an 02 540 sport touring before the A6 and loved it, but couldn't get on with the next gen E60?. Anyway, back in the fold and with my first diesel (A6 was doing £90 a week in juice running kids around)
Bearing in mind the A6 was a 4.2 V8, the Bmw is Awesome, with unreal mid range, and twice the MPG.
Just miss some goodies, and would like to retro fit a better loud speaker set up as this is crap standard compared to Audi, and Bluetooth which it doesn't have, even though it has the wide screen nav and hard drive setup.
Is this a dealer only fix with assosiated pants at ankle height routine, or are there good but original looking aftermarket solutions?

There are aftermarket fitments that will work with the oe setup, try dension, retrofits can be coded in with the oe equipment that many indy's have....however worth checking the price at a dealer as they will do a pricematch
