I thought firmware is given by Lexus for free ! 200$ ? here the download link from Lexus America https://securedp.lexus.com/download-app/downloads

There are no updates to download from this link anymore, I tried numerous times. Also, the system reboots continuously so I cannot access the menu screen and settings to update software. Just disconnected battery and reconnected after 30 minutes and same problem is there, screen would reboot non-stop after loading the caution.

Also tried to get into the service menu but was unable to following the direction here:

Hi mec0t0

Did you have any luck figuring this out? My system is stuck in a reboot loop. I tried putting the new firmware on a USB stick but it didn't help. I suspect it's rebooting before it gets to the point where it could load new software. The dealer wants $2500 for a replacement unit!
Thanks,
Eric

Hi Eric, brought it to dealer and they had to replace entire unit. Dealer wanted $2300 but managed to work out goodwill replacement (refurb.), this is the 2nd radio replacement (1st under warranty).

Has anyone faced the rebooting and black screen issue after getting replacing the head unit?

Dealer is replacing my unit under extended warranty- hoping this solves the issue.

I had mine replaced in September '14 (IIRC), I think I've had it reboot one time since then - non-issue.
This is why I purchased the extended warranty, just in case.

Speaking of 2014, I took mine to the dealer to get a couple things tweaked. Apparently they cannot set the flasher for number of times? The default is 3 and the manual even says it can be changed to 5 or 7, but they say it's greyed out, claiming it's not available for 2014. It does have the latest version of software. They also said it isn't possible to change the seatbelt alarm, even just to quiet the "fast tone" past the initial warning.

Thanks, glad to hear that.

I'm happy I did as well, otherwise I would be paying a hefty $2500 out of pocket for the replacement.
