E36 USB & Aux in port - help needed
I plan to change the existing Alpine head unit in the e36 to an CD43 which will look more OEM

In order to bring it up to date with Bluetooth and USB in I'm going to get one of these

However rather than having wires rattling around the cabin I want to fit an e90 USB / Aux in port.

This is where the fun starts. I want to change the port so that the e90 USB port connects directly to the USB port on the eBay BT device. Similarly I want the e90 3.5mm port connects directly to the 3.5mm port on the eBay BT device.
Does anyone know how the e90 can be modified to achieve this?
Thanks
John
