I went to the dealer today. They did do a software update to the 2.2.0 although that didn't solve the problem.
The dealer called me to tell me that they completed the update. They did an off/on cycle numerous times and they could not get the problem to replicate. I felt that the update may have solved the problem since Rasputin's update seem to have done the trick for his issue.
I was about a mile away and then it happened. I lost Bluetooth connection. The interesting thing I noticed is that the Bluetooth symbol on my Droid Bionic stays blue as if it is still connected where it usually turns white when not connected to any BT device. So I decided to try a call, sure enough, it is connected although I can't hear anything, nor the Entune screen showing me any type of connection, but my phone shows the call connected with the call timer counting away. I had to choose speaker on my phone to hear my call.
So this proves that there is still some type of connection between my phone and the Entune system even though it says no BT connected.
I made my way back to the dealership to show them the exact problem. I made sure not to turn off the car to show them that this is no way going to reconnect. They brought out the tech to take a look. At first they told me that they are aware of some issues with the Entune systems and they tried all they could do until a further update was released.
I asked them to revise my work order stating that they could not repair my BT connection failing problem and that it was not just for my music, but for my hands free device as well. I also pushed the fact that my car just turned 2k miles and my concern is how long will I be down without these key features of the Entune system.
Well, they decided to replace my head unit, and would call me when it comes in to set up another appointment.
My car is a 2012 so I'm hoping that I had an early model head unit and that this replacement one will be a newer revised model with a different chip/hard drive/software or whatever is causing the BT failures.
I also believe that Toyota will replace the head unit this time, but if the new one fails, they most likely make me wait till they have a permanent fix cause it sure seemed like they were pushing for me to just to deal with it until then.
I posted up my new version update even though that didn't resolve my particular problem.
They said some icons or features on the screen may look different, but I haven't noticed any difference.
