ok so i have read about this and figured it is worth posting for you all. 2016 LX Nav screen started glitching out. Got the dreaded "A program cannot be read. Please consult to a dealer." error message on the navigation display. Took it to a dealer. $6k quote to replace the navigation system after a $275 diagnosis and all the usual steps to rule out any issues. I found a service on eBay for $850 to repair the unit by typing in the error message in eBay search. Took less than a week to ship it out, repair the main navigation unit, and ship it back to me. I buttoned it back up and it worked like it was 2016 all over again. But while I had the dash all apart I figured I should at least try the new Hamilton system with touchscreen and man it is awesome. 360 camera works. Touchscreen is great. Wireless carplay is great. Steering wheel controls perfect. All in all I have a totally new driving experience for less than $2500 which a lot less than the $6k the dealer quoted and about $70k less than getting into an LX600 (which I almost did). Hope this helps someone!
