Parrot phone and steering wheel controls...DIY fit?

[Hard-Drive]

I've just taken delivery of my new 3 series this morning and I want to install one of those Parrot car kits that has the integration to the steering wheel controls.

I've managed to DIY fit my old Parrot 3200LS into my old shape (2004) 3 series and my VW Bora before that with no issues...is the new shape 3 easy to do?

Any advice welcome...thanks in advance!
