You are the smart one here; your issue was fixed, and you got free bagels/donuts and coffee!

 

Nothing is free at the stealer

 

Showed up to dealer. Saw general manager, explained how long I have been a customer and how many Lexus cars I have had, he pushed me through. In and out in 15 minutes!!!

 

I got mine rebooted at work. Took no more than 5 mins.

Talked to the service guys, they said it should be a permanent fix. No customers had returned back angry that their Nav system f-ed up again.

 

Pulling the Radio fuse also works to reset. I just did mine that way. IMO Easier than disconnecting battery terminal.

 

where is the radio fuse

 

Fuse box is behind the trunk release button

 

Hmm... ive been out of the country since saturday...i wonder when i return home in 10 days my nav would start freaking out when i turn it on for the first time

 

Yep I had same problem

 

Yes, Lexus said the cause was due to bad data from the weather and traffic data feed and the nav computer not properly handling bad data. The data source has been corrected, so now resetting the unit works. I hope they will issue a software update to do stricter checking of data so it is just ignored instead of causing the unit to fail. Fortunately I was not half way to Timbuktu when it failed. :-)

Model years affected: 2014-16

 

I agree.
I recall from my early computer network programming days (a good 30 years ago) it was one of the key requirements how to handle corrupted data - if you can't do anything smarter - do nothing (flush the data) but crashing was a sign of a seriously flawed software.

 

And even more important these days with so many people hell-bent on OTA attacks. Yes, it's Programming 101 - handle bad data, even if that simply means ignoring the data and waiting for the next packet. I bought Lexus for the quality... That has to extend to software in their components too.

 

Weird, 2014 is350 here. Day 2 of this debacle and my nav didn't have any of these problems. I think its really weird that there are some nav systems out there that wasn't affected by this glitch. Least I know what to do if it happens within the next couple days.

 

I haven't drove my car for few days now. Am I being affected or should I wait until the problem is resolved?

 

On an IS350 equipped with navigation, do you have to subscribe and pay a monthly fee to keep navigation active (like Xm), or is it self-contained and always-on? Or does it utilize your cellphone data...or what?
