What do you guys think? Would it be a good choice to replace the factory radio with?
Will it fit properly?

here's an img

 

Not positive if it will fit properly but it looks good.

 

What year are you looking to replace?

I just purchased a 2006 S40 and am wanting to add Sirius, however I am thinking changing the head unit out is a deal breaker for me since I would lose the controls for the heat and ac are displayed through there. Probably something like a plug and play unit will be in my future. *sigh*
