Hello again,
The BMW Link App is FREE from the German iTunes store, just that its a 1.8 GB download.
The link for Baum-BMW is:
Here
Yes you can use the BMW Link App without the Station, but you will not be able to listen to music via the car speakers and will not be able to charge the Iphone.
Connecting it through the USB+Aux port will however enable you to both charge the phone and listen to the music via the speakers. However the music will not stop if you receive a phone call.
My car does have the Bluetooth preparation and hands free telephone prep.
The Iphone station comes with the following: Cradle to mount the Iphone + the wire harness and end connectors to hook it up with the BMW Radio. It also has a control unit.
Here is the the link to the
BMW website:
Please let me know if you have any more questions.
Good Luck
