I have an 05 plate E60 5 series with factory bluetooth installed, which i'm completely over the moon with. However the bluetooth does not work and after having a diagnostic ran on the car the findings were that the module on the left hand side of the boot is knackered. I removed the one out the car and looked to find another on the internet. I managed to find some however they all seem to have a different model number to mine ( 84.21 6-975173-01 ). Will these other ones work or do i need the same type as was already in?
Thanks for any help
