Reprogramming after USB interface installation
 

It exists an USB-Ipod Interface for BMW X5 E70 in DENSION

This interface emulates the CD changer and is connected to the car via fibre optical of the CD Changer (MOST)

If my car is not programmed for CD changer I will need a reprogramming.

I wonder if it would be possible reprogramming my car for CD changer without a CD charger but with just an interface not BMW brand.

(sorry for my bad english)

yeah, for a small fee, the dealer will reprogram your progman for the cd changer.

you dont need reprograming, car system automaticaly detects cd-changer
