I bought the truck new and the text feature has never worked. Bought truck in September 2016 (it's an SR5 with Prem. radio w/ Nav). Anyway, went to the dealership today to see if there's a firmware update (there was). But did not fix text issue. A young IT guy comes out - Poof - fixed. So, if you can't get the truck to READ a text for you (you have to use Siri), then this is the key. Click Apps, Click Messages, it will ask "do you want to set up?" - Yes. Here's where the magic works. It will have a dialog box that comes up that says, " You may have to ..... work your phone..." or something like that. When that dialog box is up, then and only then do you click on the setting for notifications on your iPhone (under Bluetooth, and under the Toyota vehicle that your in menu.) If you click on Notifications on your phone before or after that dialog box, then it wont function correctly. You Tube, Mike C, Hands free texting.
