2007 Toyota Camry Speedometer swap advice

Hello, I own a 07 camry se 4cyl. I am attempting to make a modification to the speedometer. I found an 07 xle 4cyl speedo with the multi info display. I am wondering if it will fit and wire correctly to my current wiring. Also would the multi info display work? Will the ecu put my mileage on the new speedo for me? I am going to order the some steering wheel control buttons from an 07 solara which include a display button. I figure they will work because the solara has the same 3 spoke wheel as my camry. I found some steering controls that also have the bluetooth buttons because my camry already has them as well. Would the solara steering buttons work with my wheel? Also would the display button work correctly with my new speedometer? Thank you for your help.
