I have my DSP5 all set up, and i went to my truck to load the new calibration and O.S. and the button was grey. I could only load the calibration. So I said to myself "what the hell is going on here?" First of all I know that my cable will do it, because I have done it before. So then I asked myself "well I wonder if my other tunes will do it," remembering that I have always seen the button, "maybe something is just messed up with my DSP5." Nope, now none of my tunes have that option, the button is still grey. Does anyone have any suggestions for me?

Thanks
Zach

Did you hook it up to the truck before you tried opening the tune...I've had that happen its like it doesn't recognize that its a different operating system.

YES! Thank you

Glad you got it sorted. You need to ensure the USB is plugged in.
