Watching my favorite utube video, which includes the Livermore one DP. The clearance granted included V244 to ALTAM to Manteca. I happen to have an IFR GPS, but for sake of the question assume I'm using dual VOR and a VFR GPS for SA. How do I define V244 in the GPS? Should I use OBS mode defined by the VOR radial? I've tried following some approaches and DPs with foreflight; I don't think it does it.
