I would like to learn if an unapproved phone is able to work with an e60 MOST system, will there be any corrolation to expect it or tweak something to make it also work under an e86 iBus system?

the phone is a nokia e61 which has been documented to work (even though it's not approved) on an e60 530xd which has the new MOST and CAN-Bus system. However the new z4 M coupe is based on the e46 and the i-Bus system.

is there any way to expect the nokia e61 to work on the e86 M (z4 coupe) if it works on the e60 bmw?
