did you get all the bits you were needing to install the unit
I'm using the head unit i bought a year ago for my prev car, it's white/blue lit rather than red, but i like it too much to ditch it. Here's the info on it Sony MEX-BT500
As for the cables, I'm assuming it's a straight swap, but won't know til i take the existing unit out and I'm not doing that until i've got all the parts to finish the job off properly, so will post back when I've done it...
