I have an 09, pretty much the same headunit. The only way to get what you're looking for is to replace the HU. Crutchfield has a full write up on everything you'd need to replace it and still maintain the steering wheel controls, and also the Alpine system if you have it (mine does).
I've looked into it and done some research, but in the end , the stock HU works well enough for me now. In the future I might upgrade for the SD/USB/BT, but the BT phone part works better than anything else I've ever owned, and I just load the HD with all my stuff and head out. There's a place that sells a bigger HD for these, but I haven't filled the one I have yet.
