Like everyone's else, why do a nav update if you planned on trading in the car for a new one? Like throwing away your money.

Personally I couldn't downgrade to an ES, next car for me would have to be an LS.

Geez oh Pete. Given the level of suspicion around here I'll give a play by play.

To begin, I've owned 30+ cars in my life so you can say that I'm always looking . . . .

On the day in question I stopped by the dealership to look at a '16 LS460 CPO. The dealership had recently taken it in on trade with the color combo and options that I wanted. It also had <5k miles. When I arrived I didn't see it on the lot . . . I found out later that a manager had driven it home. Anyway, I asked for my salesman, who wasn't there yet. He's usually there by 8 am each day so I figured that something was wrong. He eventually arrived and got the keys for the LS. He was late because he's dealing with a mold problem in his house. He also told me that his wife had recently died. Anyway, he gave the the keys to the LS and told me to take it for a test drive. I didn't like it; not to mention that I could tell that it'd been a smoker's car. He asked me what I thought about the new '18 LS . . . I said that I thought it looked awful and that it had horrible reviews. He said that sales on it were pitiful. But then he said, "Have you seen the new ES?" I said that I'd done some research on the car, but that I'd found my prior ESs to be somewhat boring. He told me that I should really take a look. I went outside to look at a few but didn't test drive one. I had some free time before an early lunch meeting so I said that I might as well see if the parts dept. had the nav update for the GS. I'd called them in early Nov. and they told me to check back in a few weeks. So I figured that I could do the update before my lunch meeting.

So again I didn't go the dealership determined to buy anything. If I'd liked the LS, I would've bought it. The nav saga with the GS nudged me to look at the ES, which I liked. So I bought one.

In the OP's defense(?), he/she seems to change vehicles at a regular pace. https://acurazine.com/forums/third-g...sh-awd-976122/

In a way! It is a well known fact, any software/firmware update can run in to unexpected problem(s)
Good update programs suppose to give a way to back down or recover from the unexpected disaster.
My hunch is SD card had an uncorrectable read error causing a program hang. But still I can't
guess what is the cause of killing whole head unit. Lexus software engineers better look at incident
like this to prevent same thing happening to some one else.

if anything happen in the middle of updating a headunit software and something happen, you need to replace the whole headunit. doing the software update on your own is at ur own risk. if you tell the dealership to do it and they screw up they will have to replace it at their own expense.

bclexus

That is correct. If there is a hiccup in the middle of updating it can cause havoc. That is why the engine is kept running during the entire map updating process when Lexus does it.

Well written softwre won't cause total disaster. If that is the case, they better have a warning sticker on the SD card. I am retired now but spent~40 years in the IT field.
as a system support support specialist.
I can't even dream about software update without recovery routine. This recovery method may be not for ordinary consumer(hidden) but trained specialist's job.
How about Lexus software engineer reloading the whole system for the head unit? I believe it is possible. In real life we see unthinkable things happen from now them.

Agreed with your assessment. However, not all use cases can be considered - there will always be some edge or outlier cases that cannot be anticipated but because the OP did the install himself, he unfortunately becomes responsible...i'm sure there is a Lexus tech that can investigate but it may not even be worth their time and its definitely easier to replace than to spend hours/hours investigating a glitch that affects such a small percentage of folks.

In another real world example, there is an existing issue with some Pixel 1 Google branded phones that came out in 2016 that causes the phone to become unusable once the OS is updated to the latest version. This has probably happened to a few hundred devices per region - but not enough for Google to fix it...they'll replace your device with a new motherboard running the old OS (most of time at your cost outside of warranty)...

The point being that you can either: stay on the older version that works OR get a new phone as they've deemed it too small of an issue to spend $$$ and are willing to take any negative publicity because their sales in other areas are strong enough to withstand any negativity coming from the less than 1% case.

I feel like Lexus would always take the same stance as Google....and did just that in this instance as they CPO'd the OP's "Defective" GS, got a new head unit and they likely still manged to sell the car for a profit!
