questions about changing the stock head unit

If i was to change my head unit would i still be able to use the controls on the steering wheel?

And does anyone have suggestions on which head unit i should get...i was thinking about a double din sized so that i wouldn't have an empty slot.

Thanks

Im not sure but Im almost positive that there would be a unit that will interface, try crutchfield they are who I deal with on stero matters,

There is an adapter you can buy so you can use the steering wheel buttons with an aftermarket deck. But i think it is something around $150 personally i chose to reach over and change the stations/tracks by hand...$150 can be used towards a lot more in my opinion.

I have a pioneer Deh-p2600 I got it at best buy for i believe $160 or around that. then $40 for installation. I really like it, and it has enough power to make my speakers sound good and works well with my 12'' subwoofer.
