This is the mount for the phone cradle, you still need the part to hold a phone (mostly old bricks) but i think you can find ones for an iPhone 4, I’m seen people modify them. There is also a universal adaptor which i think allows you to connect your phone via bluetooth. The owners manual for my A3 any car with a phone system will be able to connect via Bluetooth but I’m not sure of this is true and you need to plug the phone into the cradle in order to connect. Even then I think its just for calls not media. Hope this helps.
