Look in the owner manual the code for the Bluetooth is there. Before that go to phone then to Bluetooth and connect phone make sure your Bluetooth is on your phone ones you find your phone connected and put in the code it be in the owner manual. If that still doesn't work disconnected the battery for about 5 to 10 minutes it should reset the system.
The keys at the bottom of the screen are all disabled ( on /off , home menu , Nav , phone , audio / video & mode bottom ) all of it not working what should I do ?
