Recall Beware

[FlynnZero]

I saw a thread on the recall upgrade on here. I am putting out additional alerts. Those who do not know, if you do the recall it may fry your head unit, the Nav specifically. I took mine in for the recall and they fried my head unit. The dealer did two before me with no issues. Pure speculation, but some think the dealer did something incorrect and some think the units are faulty. Not sure, but I am now waiting for a new head unit. I do like the upgrade for Carplay. Its full screen! Anyway when you take your car in, make mention of it before the upgrade. Maybe the dealer will further precautions?? Not sure exactly the cause and my guess Toyota isn't telling us.

It's a bug. Updating firmware is -hard- and always error prone. I doubt it's anything specific that the dealers are doing, but more something in the process. Writing to EPROM is tricky. Everytime I have to update firmware on -anything- I own, computer, TV, stereo, vacuum, -whatever- I always say a few prayers and hope for the best.

I also worked at an IoT company for a while where we had to update the firmware 100s of 1000s of IoT devices from time to time. The success rate was considered good if we didn't brick .1% or ~700 of them.

That's my thought as well.
