HTC One X Bluetooth will not pair to 2015 Toyota on board system

[AC Question]

HTC One X will pair phone calls and contact list but will not handle messaging

Bluetooth is a means of transferring data from one device to another. The format of that data is only very loosely specified, so one device may not accept the data from another device for the same service. About all you can do is see if Toyota has an update for their radio so it will do texts with an HTC One X. The phone was designed in 2011, the car was designed in 2014, so they may not ever work together. (That's 2 or 3 generations in Bluetooth data formats.)
