Astrotracer-Bulb mode...long exposure

Good day. K1 purchased (new) in 2018: GPS, Astrotracer, Precision Calibration-all in place and working. Bulb mode is set and active: On the monitor (top left) Astro Icon in place; on Monitor low right an additional Astro Icon will have a check mark in place contingent on pressing the round green button. Green button press also allows Bulb mode to appear on Monitor or Bulb mode not appear on Monitor and in its place shutter time exposure visible. Question: For Astrotracer to perform optimally (exposures over 30 seconds but certainly less than 90 seconds) do I need to have the lower right Astrotracer Icon reflect the check mark in the box and in doing so am I forced to use the Bulb mode as a true manual exposure? Likely, there are a few relationship variables between having or not having the check mark appearing in the Atrotracer box on lower right monitor. Thank you.

Most people forget to turn on the GPS engine via the button on the righthand side of the viewfinder hump. If you do that all should fall into place.

Funny you should mention that. I did just that (forgot to turn on GPS) on my first attempt to use AT! In my opinion, turning on AT should automatically turn on GPS, but anyway...
