Not sure if anyone else noticed this (or cares), and it may have already been discussed but I didn't see it, but Lexus updated their Pre-Order Guide for the 550 recently. I had downloaded the original version back in June (which interestingly enough, was originally called "MY23-Lexus-GX-POG" instead of MY24) and I compared it to the new version and there are a few changes. As much of a GX nerd as I am, I mainly looked at the model comparison page - not the entire brochure.
Last page of original version was P4-7665 (06/23), newer version: P4-7665v2 (11/23).
Changes:
GX Premium - old version said "Interior ambient illumination" and now says "Ambient illumination", options now include Wireless phone charger
GX Premium+ - options added SmartAccess card key under Digital Key
GX Luxury - Towing capacity increased from 6990 lb to 7145 lb, added SmartAccess card key under Digital Key
GX Luxury+ - Towing capacity increased from 6780 lb to 6955 lb, added SmartAccess card key under Digital Key
GX Overtrail - options now include Wireless phone charger, Without moonroof
GX Overtrail+ - options added SmartAccess card key under Digital Key, Without moonroof
There are a few more details I noticed are different, including the disclaimers on the last page - one that caught my eye was it now says "...Android Auto requires a compatible Android 11.0+ phone..." so I'm thinking older phones are not going to work. Other thing of note (that I saw), they added #19 in the updated POG to talk about the engine immoblizer.
