move the radio and put it under your seat maybe?? it looks like you have a cupholder that slides out? if so pull the cupholder out and make a housing for your heater and ac controls and fiberglass it in there. than you have room for a nice 8 inch screen!! thats what did in my truck..relocated radio to center console armrest..relocated heater controls to glove compartment and used the space for my 8 inch lilliput touchscreen. i recomended puting it in the cupholder spot because this way you dont have to extend the ac wiring.
