Securing Eonon / Pumpkin / DYN(AVIN) Aftermarket Head Units

[we350z]

Finally getting around to installing my Eonon GA5166 head unit just wondering how folks have gone about securing it? I know a lot of the aftermarket units pretty much have the same built-in bezel not a separate, removable one like the stock unit. I've read about folks cutting the foam from the packaging to wedge it in there but is there anything else one can do (i.e. Velcro strips, etc...)?

I used the 4 screws on the bottom of my 16:9 boardmonitor plus two zip ties in the top corners to secure my stock HU.

I don't see how you could use zip ties at all with these...
