I didn't see anyone else have an issue with the entune update, so I wanted to share my experience. Like many of you I received the Entune update email and waited patiently for the stick to arrive in the mail. Once it did, I followed the simple instructions and unfortunately the update did not install. It got to step 6 and then and error code showed up on the screen. I tried it a few more times and the same thing happened. I called Toyota's customer service and they said that other people had had the same issue with the software and that they would send me a new stick with better software. I waited for two weeks and I never received it. Finally, I called them again and asked if I could take it to a dealer and have them install the update because I was planning to travel. I made an appointment with my dealer (Los Angeles) and they tried to install the update with their own stick and it didn't work. After a few hours of the techs working on it, they told me that they had to replace the unit. Unfortunately, I had to tell them not to order the part because I was traveling out of town and that I would take it to a dealer where I was going (Salt Lake City). This past Monday I took it to the dealer and explained what had happened. They said they had to look at it again. After an hour the Service Advisor explained that "the system was in limbo, like when you turn on a computer and the screen goes blue and you can't do anything." He said that he would need time time to fix it because to replace the unit would cost $10,000 and that the techs would have to call the Toyota Entune people about it. After 4 hours, he finally said that they were unable to fix it and would have to order the unit and replace it. It's supposed to come in on Friday and I'm hoping to have it installed Saturday or Monday. This whole time the only thing that has worked is the radio. The screen is either black or it says "In software update mode: Please install software stick." I can't charge my phone through the USB, or use it with the AUX cable. I also have no access to any apps. More than anything it's been a hassle, especially since I had to travel. But it's all covered by the warranty. I will update when it is fixed.
