Will this fit the X5?

I have a DSP system, is that going to make my installation difficult? I am used to just opening up the front and swapping out the headunits. Is there more required for this in the X5?

Do I have to pull wires from somewhere?

Ive found it for around $1,000. I think it is an excellent deal.

Any help will be appreciated.
Thanks guys.
