Do you know the password? To enter text you need the parking brake set. If your headunit did not get installed correctly with a parking brake sensor, then your best course of action is to use my Security Password Removal script in the Hacks section .

Yes I have the password and the handbrake is on but it won't allow me to do anything on the screen will eject the cd that's it was fully working before battery swapped nothing else touched

First, remove the password using my script. That will get you access to the radio. Then if you feel that something isn't right when accessing some menus you can test whether the handbrake connection is bad. There is a settings screen where it displays the status of various things, including the state of the parking brake.

How do you remove the password? What's my script

Since you have an F940-BT I moved this thread to the correct F series sub-forum. In the Hacks/Mods section you'll find Security Password Removal Script

Thanks unfortunately I don't have a computer or sd card just my phone so looks like I'll be getting a new radio
