Today I installed a pretty cool little wireless adapter that works great for lossless audio. (I have actually been using it for about 3 weeks but I finally hid it today) I will attach pics to this post of the install. I have a 2012 R60s with the HK system but I do not have Mini Connected. Found this device while reading a thread on Reddit about different wireless solutions others have tried. Here is a link to it on Amazon.
The thing that makes this device different is it is WiFi and uses Air Play instead of Bluetooth. This means it sounds better than Bluetooth because there is no compression. It takes about 10-15 seconds to boot up. To make things better it only cost about $20.00!

If you decide to purchase just make sure to update the firmware and watch the video on Amazon about how to link it to your iPhone.

So to hide the device I just bought a new USB/AUX IN socket (cost me about $50, my original was giving me some problems anyway) Here is a link http://parts.miniofkennesaw.com/show...ssembly=423868
I then took the new socket and connected it to the factory wires.
Then I used the new socket to plug in the wireless adapter and hid it under the gearshifter boot. I left the old socket in the original location even though it is useless now. This adapter will also work just sitting in the center rail if you don't want to hide it. I just hate wires showing anywhere in my car.

See pics....

 

Does this allow you to use all the functions of your iphone such as playlists, skip back and forth on tracks ect?

 

Yep, I have not found anything I can't do with it on my phone. Steering wheel controls don't work with it other than volume though.
