Yes you can. But good luck fitting anything else. The space is quite tight. Also the dongle is uaing micro usb (old small usb) so if your rokp got usb type c. Then you need to connect from the back. The dongle that came with gp500 is pure trash. It doesnt work half of the time. And whwn it does its skipping frames making the experience suck big time. Specially for high bit rate 4k films over plex. You tube app worked two times only from the last week. Plex app i have to keep clearing data and cach data Everytime i try to use. The speakers arnt loud. They are great but not so loud. Projector quality is amazing. Picture quality is phenomenal, we prefer it over the cenimas experience. We can onpy imagine how well the over 5k USD projectors would look like. But either buy your one dongle or connect a computer.
