Honda Sat Nav?

03 CRV .. Dvd gave the normal error on screen but the disc would not eject, finally got it out ( did scratch it though)
Have removed the unit which was straight forward, have removed the two screws each side to remove the screen which does move in and out of the unit at the bottom but the top section remains firm, there looks like two tags at the side of the unit which may be holding the screen in place or do you have to remove other parts to remove the screen.
Thanks
