I had a query (http://www.xoutpost.com/bluetooth/518...ctivation.html) recently that concluded that I had a Telematic Control Unit (TCU) for my Bluetooth capabilities rather than a ULF and as such could not use Navcoder to activate Voice Recognition.

So I decided to swap the TCU for a ULF as I wanted Voice Recognition, the ability to pair to latest phones etc...

Well, I've got my shiny new 13th generation ULF and have ripped the boot liner out and expected a simple plug-for-plug swap.

However, the TCU seems to have a couple of additional antennae connections (see photos) one of which is in use - is that simply for the telematics and as such can be ignored if I'm only looking for purely telephone functionality?





Should I simply connect the white connector and omit the other?

I guess I could experiment... but it's just started raining here in London, and as I lack a large enough garage, I can await your guys' help!
