2004 Nissan Pathfinder questions

2 questions guys. Truck has the factory deck with 6 disc indash changer with steering wheel controls for volume and track up and down. I dont want to lose the steering wheel controls at all. My options are keep the deck and use something like a JL Audio clean sweep or RF 3sixty or go with an aftermarket deck. Which way would you go? I have an Eclipse 8454 and would use that if I could know I wont lose my steering wheel controls. If I can go aftermarket, what interface can I use to keep my wheel controls?
