Combined stereo/satnav/bluetooth

I want to put a bluetooth carkit in my 07 plate focus zetec 1.6, I also would like to put in a satnav, is there a stereo replacement available that would do both, and while I'm being greedy play music from my iphone/ipod through bluetooth too?
I saw this online,

Can anyone recommend an alternative or a good person around London to supply and fit an alternative?
