By "GPS", I assume you mean an in-dash car stereo with built-in GPS. Based on that assumption, you first need to know that car stereo comes in two sizes: DIN and Double-DIN. A DIN unit is a normal-sized after-market car stereo. If you walk in to Wal-Mart, look at the $100 car stereos, all those are DIN-sized units. If that's roughly the same size as your factory car stereo, you're pretty much good to go to swap it out for a better after-market system that is also a DIN-size. Double-DIN is simply twice as big. If the entire car stereo section of your dash is roughly that size, then again, you're good to go.
Problem is, many factory stereos are what's known as "DIN-and-a-half", which is pretty much just what it sounds like... bigger than DIN, but not quite as big as Double-DIN. Who knows why?
Anyway, if your stereo is Double-DIN, then you can get pretty much whatever you want. But if it's not that big (DIN or DIN 1/2), then you'll need to get a single-DIN unit with a flip-up face. It looks like a regular DIN-size unit, but you can press a button and a six- or seven-inch screen will come out like a CD, and then angle itself up. Depending on your car, that might mean it's covering AC controls or something else you might want to get to. While these units tend to be pretty high-end (pricey), they'll also be full featured, including the ability to integrate with existing steering wheel controls. The only thing is, if your stereo unit happens to be right in front of your gear-stick, there needs to be enough space for the screen to fully extend before flipping up. If you have less than a DD, and it's right in front of the stick, then you, my friend, are Plumb Out Of Luck.
Beyond all this, all major manufacturers offer GPS, Bluetooth, built-in apps, touchscreen, integration with back-up camera, and, yes, integration with existing steering wheel controls. Hope this was helpful!
