I have a MFSW(multi-function steering wheel) and a nav in the center of my car.
I have been thinking to retrofit the bluetooth function on my MFSW for a long long time and I even went on ebay bidding a 2006 OEM bluetooh kit that someone was selling for like 400 bucks but I did not win.
I then started my research of finding a proper solution then I came cross newministuff.com and bought a Evo kit.
Why Evo kit, because I don't need a small screen tells me the caller ID since most of the smart phones nowadays can announce the caller name by default ( my phone is a Galaxy S2). However, Evo kit was an old product although most of the youtube or BMW forum DIY using Evo kit succesfully but still, the bluetooth technology in CK3000 has been outdated and I had problem with some odd re-dial screen stuck on my nav when I press the R/T button and bad bluetooth performance on my Android (drops).

I returned it to Mike at newministuff and bought a MKi9000 instead. This time the MKi9000 has better voice quality and it comes better microphone ( I concealed it on the sun roof button but I switched the position to right) and easy firmware/software update feature through USB so it can keep up the interoperability with new phones while CK3000 can't and bad interop with my Android phones.
The Mki9000 is finally working fine with my MFSW and the voice quality is superb.
Thanks for the patience from Mike (newministuff), we exchanged many emails and he was very helpful to guide me through the settings.
I am happy now...actually..my wife is happy that she can now using MFSW to pick up/reject calls from the steering wheel phone button while she is driving.
Just wanted to share my experience with the vender and the model I chose for the bluetooth retrofit kit. The kit comes with very easy connectors and require absolutely no cutting or re-wiring, the tricky part is to connect the MFSW module to sync with Parrot unit..but it all worked out fine if you follow the instruction.

 

Mikey is awesome and very helpful with anything you need. Glad you got your BT stuff working.
