hi i was wondering if anybody can help me...

I had my car (54 reg focus) broken into on thurs night and had my STANDARD ford cd/stereo stolen... (who steals a standard ford stereo???!!!!!!)

the stereo i had was the 6000 black one with the volume knob on the left which u push in and out to turn it on and off.

i've seen a replacemetn 6000 black stereo but its got a on/off button instead of pushing the volume knob in.

will this work perfectly with my car? and will the steering wheel controls work with it?
