Hi there,
I assume that the cig lighter cover is removed with a small screwdriver or like to reveal a screw that retains the larger radio surround.
yes, that is correct
Once removed I guess that the larger section can then be popped out of place.
Yes. IIRC, it pops off, but be sure to look for screws first. I haven't done this since the last time we shipped the truck two years ago.
I do this every time we ship to strip the cab of all the radios, etc. It only takes a few minutes once you are familiar with the process. Allow 10-15 minutes the first time. Take your time and look around. Between the manual and the photos, you should have no issues.
Thankfully, the entire dash / cab is easy to disassemble for a non-professional mechanic like myself.
If you've got the time, an excellent upgrade of the cab is to remove the seats, headliner and floor mat and line the cab with acoustic mat. It quiets the cab significantly and also reduces the load on the air conditioner a bit.
You can strip the cab in an hour or two.
The only tricky bit is the snap-pin connectors that are used to hold some of the interior trim pieces. You'll need a pry bar about 20cm long for some of those. We took an old flatblade screwdriver and cut a V notch in the end and bent the end to about a 10 degree angle. It made a perfect tool for the job.
If you are mounting additional speakers, you'll have the cab stripped out anyway, so that is a perfect time to line it with acoustic mat.
It's also the perfect time to install & route cables for map lights, 12/24VDC power distribution, radio antennas, GPS antennas, satellite phone antennas, etc.
If you want to go all-out on the sound system, it is possible to do in the FG cab. We mounted high-quality replacement speakers/drivers in the door, smaller diameter speakers/drivers in the upper rear corners of the cab and also put a big subwoofer in our center console. The controller & GPS for the head end and the power amp mounted in the base of the console hidden by a false floor (controller & GPS) and in a side compartment of the console (power amp). The iPod mounted via velcro in the center console. The system was spec'ed and initially installed by a friend of a friend who installed sound systems in ski boats. The system sounds great, but it was overkill for us, since we don't do a lot of high-volume rockin' anymore.
In addition, I needed to re-wire every single thing the kid did. Lesson: You'll be better off doing your own work than letting someone do it who is accustomed to doing street vehicle installs. Do not use cheap connectors. We used marine grade crimp/heat-shrink adhesive connectors for all of our wiring. Expensive, but they stay connected in off-road / overlanding use.
You will find photos of all of those installs, parts, etc. in the buildup photo albums.

This build will look pretty amateurish by your OZ standards. Had I known at the time ATW and the other FG builders existed down there, we would have just shipped our chassis to OZ and had them install one of their proven camper boxes on it. As we say up here: Live and learn.
