I'm glad I'm not the only one lately having this issue.
Since iOS 11, the head unit has been acting like a spoiled brat, intermittently giving me a connection error every time I connect via USB. Now that I have an iPhoneX with 11.1.2, I've had some interesting issues.
I switched to spotify from apple music this weekend. I deleted my apple music app since they allow us to do that now. Well, apparently the apple music app is how our head units access our phones. The app makes our phone appear as if it were an ipod and allows the head unit to gain control that way. Once I reinstalled the apple music app, it recognized the device.... sporadically.
Now without fail, every time I plug in my phone to the USB (which is my workflow, please don't tell me to just use bluetooth) I get a "failed to connect" error. I have to have something playing on the phone, and then the head unit will decide whether or not to connect.
I took a couple swats at a fix which included:
- Updating the Entune software once successfully connected to the head unit.
- Discovering there's a head unit firmware update thanks to a reddit commenter. Updated firmware via a USB thumbdrive.
Neither of these updates did anything cosmetic to the Entune functionality or the head unit functionality. I am still getting frequent connection errors when plugging the phone in via USB.
I have no faith at all in my dealer to understand or even know what the hell I am talking about if I were to take this in. Last time I had technical request, their one "computer" guy didn't know how to change the default settings I requested to have changed out of the owner's manual.
Later when I asked if there was a software update for the head unit, the same one and only "computer guy" didn't understand that I was talking about something other than the $170 map update. He literally didn't know the head unit software and mapping were two totally different things. He told me "I just plug my laptop into the car and click where it tells me to click."
