Have 2015 Luxury GX 460. Purchased Jan 23, 2015. Build date Dec 14. On a couple of occasions when using the USB drive the music stopped. Tried different methods to restart. The only one that worked was removing the Flash Drive, turning off the vehicle power and then restarting and reinserting the flash drive. Discussed with dealer yesterday and they stated there is another firmware update in process and should be at the dealers by the end of the year. Luckily it only happens once in a while.

 

I was going to tell you to have the firmware updated on your vehicle. I need to have this done on mine as well, waiting until I need maintenance before going in. I live 110 miles each direction from the dealer. I have my navigation screen freeze up every so often as well.

 

The entire screen does not freeze up. Just the Flash Drive in the USB stops working. My VIN number was not in the range of the firmware update for screen freeze. That is why they say this will be covered in a future firmware update.

 

Okay, keep us posted. Mine doesn't freeze up that often...
