Well its taken sometime and after a few weeks of trying everything, I didnt have the right tools to check voltage etc so took the car in to a local specialist. It was down to the iBus signal as stated in this thread so many thanks to that. looks like a broken wire which was fixed and all working now.

Now on to the telephone bluetooth from what I have been told seems like its the module in the back everything else checks out but the unit will not go into pair mode even with the MBW scanner software.
