Welcome to the forum,

Try deleting the phone and starting again.

To delete the phone, press and hold the button in the centre console for 3 seconds, turn ign to stage 1, the release the button and immediately re-press the button then wait 10 seconds and the display should say something like phones deleted.

Also don't have more than 10 sms txt messages stored in the phone.

What type of phone is it? and what version of ULF do you have?.
