This is the JP1 beginners forum. There's no such thing as a stupid question in here, so post away, but this forum is just for JP1 users and people considering JP1, non-JP1 users please use the appropriate forum above!

Getting the cable is a good idea. It is useful for a lot more than just installing that upgrade and it makes installing the upgrade easier. But the 8910 can have upgrades installed by .wav file. So you can use the same free software needed to install via cable and instead create a .wav file to install via your PC's speakers (no purchases required, but harder to do than via JP1 cable).
