I have an X50v and already have resco explorer v5.14. I was trying to upgrade to v5.15 but not sure which install bundle to use.

Explorer2003_p (1,637KB)
or
Explorer2003_p03 (647KB)

I found out thatthe space required for installation to the PPC is different:

For Explorer2003_p03: Space Required on Device: 1325KB

For Explorer2003_p: Space Required on Device: 980KB

You can try it yourself. The info above appears right after the license aggrement. Let me know which file i should install on my x50v.

Explorer2003_p is for PPC2002
Explorer2003_p03 is for WM2003

For your X50v you'll want the second one.
