Capture ILS with Challenger 650

[N53E]

Hope this is the right place for this question. I'm having a problem getting an ILS capture in the CL650. The video that I can find talk about an automatic change from FMS to AN ILS. This does not happen for me. I do not get the double blue dashes to show capture. I have pressed APPR and the fun starts. High speed and way too high. I've changed from setting the altitude at IAF/IF to FAF. This appears to have helped with speed and GS. Is that correct?  I have not even attempted an RNAV yet. I have gone through the CDU menus both iiin the beginning and descent. I even set the ILS frequency in NAV1, even though it supposed to be automatic. I like my interceptions to be around 45 degrees, however most have been at 90 degrees. Thanks Sim Brief, guess I should change this.  Any help for the approaches are appreciated. Distance speed and flap setting also helpful.

You still should set appropriate speeds.

But I am also yet to understand the autotune (nav-to-nav) functionality. I've found this thread which contains many hints:
