1. Basic audio (no Nav) - amp in dash as part of CD Player/Radio - 6M cable NOT required
2. Premium Audio - (with or without Nav) - amp in trunk - 6m cable IS required
3. DSP - (with or without Nav) - amp in trunk - 6m cable AND iBus USB/App IS required

This is a simplified list... (and there's bound to be exceptions!) and of course, the iBus USB/App setup is a good idea, even without DSP...
Mine is DSP with Mid and Business CD (no NAV) and did not need the 6M cable. Probably should add a #4 to your list.

1. Basic audio (no Nav) - amp in dash as part of CD Player/Radio - 6M cable NOT required
2. Premium Audio - (with or without Nav) - amp in trunk - 6m cable IS required
3. DSP - (with Nav) - amp in trunk - 6m cable AND iBus USB/App IS required
4. DSP (without nav) - amp in trunk - 6m cable not needed BUT iBus USB/App IS required
