Let's not write any ASAPs over this. I am here to help. The following is only what they call a technique for all y'all new aviators out there. Sure you can go to green needles and just shoot the raw ILS and read out the DME. That's the easy way actually. But for us who like to actually use the MFD here's what can be done.

1. When building this approach, always include the other pilot. Make it a two-pilot endeavor.
2. Preset or hard tune the localizer frequency.
3. Select a Visual Approach for that runway.
4. Delete the 5-mile fix and build the step-down fixes in any order you see fit to. In DTW I'd recommend building from the furthest straight-in and working your way to the runway. Input the altitudes and speeds.

Remember you will get no Blue Needle Preview on constructed/visual approach selections. So once on vectors:

5.Go to green needles and use the course knob, the one with algae crust on it, to center the CDI to the appropriate thing.

Don't get confused when it comes to visuals versus ILS in visual conditions. If cleared for the ILS, follow the needles until the appropriate time. If cleared for a visual, well, do what you want. It's a visual. Keep in mind that airports run ILS approaches in VMC all the time so they can keep a lot of airplanes close together so always fly the chart if cleared for the ILS. Don't confuse that.
