I have a tendency to damage plastic parts. Where are the screws located to get it out? I checked the BGB but couldn't find a guide on removal.

Thanks.

If i remember right its the same steps to remove the radio, start around the shifter boot and work up you just gotta pull the parts around the top of the unit. If you have an audio install tool they work wonders. Its been a couple years since I pulled mine to install my boost gauge but its not that bad.

Based on this pic it looks like there are screws in the top and on the 3 sides. How do I get to them?

If you pull the cluster surrround you should be able to better see. Don't forget about the blue cable that goes through the firewall.

The HVAC unit requires you to remove the trim panel below the cluster (four screws, of which two are under a clip-in trim piece below the ignition), then the bezel surrounding the cluster (screws below the HVAC unit, on the bottom side of the dash cowl, hidden behind the trim panel below the cluster; the cluster illumination dial and the driver's side vent handle pull off with a little wiggling). The HVAC unit itself is screwed into the cluster surround bezel.

There are two cables behind the HVAC panel which you have to disconnect at the far end; they're each held in with a pressure clip removable with a flathead screwdriver, and hooked over a post which a needlenose plier works well to remove.

One is a blue cable which runs through the firewall.

The other is a black cable which runs down through the centre stack and is attached just to the right of the gas pedal.

Perfect, that was super helpful. Thanks!

Ack, realized I forgot something. The blue cable is easy to replace, as Toyota thoughtfully provided a guide tube. The black cable does not have such a guide -- I usually suggest people tie a string to the far end so that when you have to reinstall it you have a guide.
