I know the battery disconnect is the current fix for the looping issue. Does anyone know which fuse I can pull that will reset the Nav/radio instead of having to disconnect the battery terminal? I already tried the radio fuse under the steering column but that didn't work.


Reason I'm asking is because the rebooting/looping issue happened to me on the way to work this morning. I don't have a wrench at the moment to access the battery terminal, and would like to get my radio working for my 1.5 hr commute home later this afternoon.


TIA

 

Power cycling the battery works for me so far.
Took a total of 5min. Hopefully it stays fixed.

 

Just went to my local dealer here in woodland hills, ca. Was a long line of cars waiting to get reset. Took about 30 minutes but seems to be fine now. I know i could have done the reset myself, but i wanted some free bagels/donuts and coffee.

I saw all types of models coming in, so it's pretty widespread.

 

Funny how this "satellite issue" only affected Lexus and newer models only.

From what I read. it was an OTA update that crashed the system.

 

Update: We apologize if your vehicle has experienced an error in the navigation head unit. Errant data broadcast by our traffic and weather data service provider was not handled as expected by the microcomputer in the vehicle navigation head unit (center display) of 2014-16 Model Year Lexus vehicles and 2016 Model Year Toyota Land Cruiser.

In some situations, this issue can cause the head unit to restart repeatedly, affecting operation of the navigation system, audio and climate control features. In addition, the back-up camera and hands-free mobile phone functions are inoperative. The data suspected to be the source of the error was corrected last night.

The correction is a forced reset and clearing of the errant data from the system.
Toyota and Lexus owners experiencing these issues should visit their dealer for a complimentary system reset and a confirmation of the system. Until then, owners of affected vehicles should exercise additional caution when driving. We regret any inconvenience to our customers.

Experiencing this too. GF calls me this morning saying "WTF is wrong with the car?" haha. Guess I have to reset this now.

 

FML. It just happened to me this morning while I was going to work. It was working fine yesterday tho.

Doesn't seem like there's any wait in my dealership tho.

Out of curiosity, what's the latest software for a 2014 IS with nav? This is what I'm running.

Yes. you only need to disconnect the negative one. (Black one).

Keep it disconnected for ~5mins, reconnect. Should be fixed.

 

I called Crown Lexus in Ontario, California yesterday and was told it would be resolved this morning. When it was not resolved, I read this forum, took out a 10 mm socket, removed the negative terminal cable for two minutes, replaced it, started the car, and a message came on that it was loading and to not turn off power. My navigation and radio now work again.
