Hi


I have 2006 Pre LCI E60 525i with Business MASK and Bluetooth phone.


I decided to retrofit the CHAMP only after shaking my head with NBT and CIC as I only need USB music and Bluetooth phone (no Bluetooth streaming).


So would it be easy to retrofit the CHAMP and is it capable of adding the MULF HIGH for USB playing in the arm rest?


Can I use the CID for CIC or I have to buy CID for CCC to fit with the CHAMP?


Thanks
