One of the toyota forums referred to the security screws being hardened, a normal drill bit hardly making a mark. Your side cutters might not grip.

You maybe able to remove the other screws and pivot the unit up and down on that screw a little and loosen it that way.

these fasteners are fairly well thought out, made that shape and form so that you really need the tool made for it to get em out, failing that. destroy the car around it. you wont be drilling them out either, hard as f. Is there any way by removing some more dash board you could get behind the screw/bolt and turn it from behind with vise grips. If you get it out maybe replace with a "rivet nut" with a 5 or 6mm thread.

hey gblack--How did you get on ? -just noticed you were in dauckland.
To be honest, I left it as my wife's car and she not worried about the dead head unit as much as me. Put it into the too hard basket for now
And of course, we now in L3 so cars not getting used a lot.
Did replace tyres and tubes on bicycle previous weekend, so back into my lockdown bike rides instead.

Battery terminal pliers. One of the most useful sets of pliers I own. May not work but these have got me out of heaps of tricky spots with similar bolts. Commonly used on aircraft as Hilok collar removal pliers. The hardened teeth grab onto sloping bolts, the harder you squeeze the tighter they grip.
mrfixit-none of those are the ford/mazda type. cabrio.There are probably a fair few options as far as being able to grip the darn things. IF you can get access. Usually they are placed so getting in around the screws is at best difficult. For me without the correct key its been luck with a snake eye driver hooking the grooves or luck with a flat blade screwdriver also grabbing the grooves.

Almost definitely "a fella in west Auckland" could sort it for you in a few minutes. I did think to suggest contacting the dealer she bought it from (recent purchase as I recall) and see if they have the "key".--It almost always comes separately in an envelope.
Hi, try not to over think it, I see these screws all the time when doing Subaru airbag recalls, just get a smallish flat blade screwdriver in the groove, twist it in between the round inner part and outer part of the groove, once its loosened a little it will come out with your fingers, chuck it in the bin and fit a standard phillips screw.

Good idea --except where they put a dob of glue/threadlocker on the thread. Then ya just bust the blade tip off or rip the mount clean outa the chassis.--ask me how I know

Probably the same way I know that 99 percent of the time I get these screws out the way I suggested. By experience.

actually way back earlier in the thread l suggested what you do .😁 but yea in a couple of Toyota’s ,s they had glued in the threads
Top bolt is Phillips, but the bottom bolt is new to me. Some sort of security head?
The aftermarket head unit in my wife's Aqua (Prius C) has stopped working; or at least the touch screen is blank. Easy to remove the facia around the double DIN unit, but I expected to see 4 Phillips head bolts holding the brackets. The bottom bolt on left and right hand side though need some sort of special socket?

Is it screwed in ? It may just be a pin to locate the holder.

are you sure thats aftermarket head unit because new cars radio are the central computer to operate a large junk of the car would explain the security bolts to stop removing vital computer parts of a car. as that what that looks to me sheer bolt so no one removes the unit.

Looks like a security head fastener, probably to deter the unit from being easily removed (as in a break-in). A Toyota workshop should have one, or a multimedia installer.

Good pair of side cutters on the edge of the head (not in a shear action!) will unscrew it.
