There is a small hidden space on the overhead, just near SOS button. Just press it and it will open. What is the purpose of this space? My toll transponder didn't fit there and I don't have a garage to open, so I am not sure if it is meant for garage door opener.
Ok got it. Prime is my first prius, so this overhead small box was a new spot for me. I started using it for my non-frequently used departmental store and keychain cards. Thanks all.
