Hi al

Firstly i dont have an e9x but an e60

i want to reto fit bluetooth to my car which has professional sat nav already factory installed.

I have found the guide for cars with no prep. A retro cable is available but alot of the connectors are not rquired as i dont want an eject box or charging facility.

I was thinking of making a custom loom. All connectors should be fine but its the 54pin plug

Does anyone have the pin outs for the connector x14133?

Also do i need a ulf or a tcu unit, what is the difference? does the fibre optic cable deal with all audio, etc?

There seems to e no direct connection to the headunit like there was on the e46 models.

Thanks for any help or advice in advance
