Switching DSP5 tunes with V2 module

[kdawg62]

Do you have to have a switch installed to be able to change tunes in the menu of the V2 module. Under the 'tuning tool' menu it has a option for switchable tunes but it says that the option is currently not available. I am running the dsp5 operating system on my lmm duramax. Any help on what it takes to change tunes with the v2 would be appreciated.
