I've been locked out of my stereo, it's the touchscreen one with built in navigation, Bluetooth and SD card on the left. It requested the code but the child had fun pressing the button trying to guess the code and locked it. It now says "please contact your dealer" (see attached image) I'd love to know how to reset the unit so I can input the correct code for it, without getting stung with a bill if it's something I can do myself. Please help me Thank you :)

Hello mate how did you got it fixed? please let us know.
