The 1958 display is a notable problem. Especially considering the competition in this size class and this $$$ class are all at 12" or greater screens. And the new 4Runner is at 14". However, absolutely none of the other LCLC options were worth it for me, and Toyota is not the best at those premium electronic options. I'll spend my own money upgrading rather than overpay Toyota to install inferior options.
RobLS, the problem with upgrading cameras is that it's going to be difficult to that with the stock head unit. OEM head units use OEM wiring harnesses. The 1958 and LCLC head units use the same harness, but it's not a harness you can easily tap into to add the missing camera feeds for your 1958. You have three options:
1) find a scrap yard that has a LCLC and if the cameras are not damaged, you'll want to trace them back to whatever harness they are plugged into. Might as well take the harness too, tracing it back to the head unit. Hopefully your 1958 has at least some of those harnesses available for you to tap into. At least at the head unit you can. Previous Toyota models like the FJ were near identical in their electrical system wiring across trim levels, making it easy to add premium options to base models. Active Traction Control for example was as easy as buying the missing dash button from Toyota Parts.
2) replace the head unit with complete aftermarket. Your new cameras will typically come with an RCA feed. Aftermarket head units typically have a RCA input(s) for camera feeds.
3) Run an additional monitor screen dedicated to the cameras. Not as clean, but you could probably mount an 8" screen on one of the side gills of the stock head unit, angled to driver. Alternatively, suction-cup it to the windshield if you're just going to be using it for off-roading visibility.
