I am going to upgrade my 06 MASK idrive system to 2011 CIC system. Want to add a module in order to use iphone via bluetooth . Want to get opinion from you. Should I buy a MULF2 module or buy a COMBOX? What is the different between them?
The CIC seller told me the MULF2 and Combox has the same function which COMBOX can access to the internet also. If I just want to have the BT function, just buy the MULF2 is ok. Is it true? Is it difficult to install?
