Hi! Anyone has experience of using Bluetooth music adaptor for AMI while connecting to the Audi’s original Bluetooth handsfree at the same time using the same phone?

I am interested in buying the ViseeO Tune2Air WMA1000 Bluetooth wireless music adaptor which claims to be working with any Audi Music Interface (AMI) with iPod options. It claims it will just work like a normal AMI except it is wireless and I don’t need to have my iPhone actually attached to the AMI or buy an extra iPod which I don’t really use often since I only use iPhone to listen to music and perform all my other tasks. As described, once connected it will allows me to display the entire music, browse the music list on the MMI screen, I can also see the song info, and control the music from the MMI control panel or steering wheel which sounds interesting as I have not come across any other product on the market that allows a wireless display of iPod library.

However, I use Audi’s Bluetooth handsfree a lot so I was wondering if I would be able to connect to the Audi’s original handsfree while connecting to Tune2Air adaptor at the same time? The webpage info seems to say ok but as I know Bluetooth is 1 to 1 connection isn't it? Has anyone got idea? Would really appreciate if anyone can help me out here. Cheers!
