I think it's a very good option :-)

I've received on saturday KIV-700 model, that is quite similar to yours but without bluetooth and I'm very happy with it so far. I think that fits very well with XF, considering it's a black unit.

My intention was to buy these trims in order to match a bit more the dash with the unit, however they've emailed me to say that they've decided to discontinue this part :-(
