On my Palazzo I had to remove the panel to access a broken fan motor. Your radio probably has 4 small holes in each corner. Insert 4 pieces of wire as thick as possible into each hole, this releases the radio clips and the radio can be pulled out. Mark and remove the wires on the back of the radio. There will probably be 4 threaded posts that hold the dash panel in place. Remove the nuts and washers and the panel should come out. Take care not to break the posts off of the panel back.
