Hey, I've been locked out of my stereo, it's the touchscreen one with built in gps, bluetooth and sd card on the left. It requested the code but the children had fun pressing the button trying to guess the code and locked it. It now says "please contact your dealer" I'd love 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. Thank you :)
