vfilipe, check out this post from "gibbo_ireland" and his posts that follow. He says he has the TCU and could not get it to pair. He ultimately got it to pair by doing something to the eject box wiring and using the eject box button. Initially, I was skeptical that he had a TCU (and really had a ULF). He never responded to posts after his success post, so we do not know what he did and what parts he really had. But, there are probably three possibilities to consider:

1. gibbo_ireland had a ULF all along (this does not do you any good)
2. The European GSM TCU requires a eject box to be connected, but not necessarily the pairing button (gibbo_ireland's use of the pairing button was merely coincidental after his eject box wiring modification)
3. The European GSM TCU requires the eject box pairing button to pair
