Becker CDR23 - ipod connection

[R33P]

Hi all, I have read numerous reviews and forums re. the Becker CDR23 - ipod connection and I just wish to clarify 100% before I purchase anything.

I believe this unit lacks an Aux socket on the rear so you have to hard wire the FM transmitter style connector via the ariel connection, correct?

I also understand that changing the head unit is difficult due to some fibre communication jiggery that works with other parts of the car, correct or rubbish?

In a nutshell, I just wish to hook up my iphone 4S and play tunes, can anyone offer some sound advice.

Many thanks!
