MMUN Arrival Question/Discussion

[Sauerbru]

Hi Everyone,

I am new here and have a question regarding this routing that I was provided via simbrief. There was no STAR provided in the initial routing which is fine but I guess my question is, how would the final leg of this flight work, typically. Below is the route that was provided:

KMIA/26L N0454F380 MAYNR2 CANOA UB879 CUN DCT MMUN/12R

I use Pilot2ATC as my means of communicating with ATC. I feel like I completely botched this arrival given that no STAR was provided and was not told by the ATC program to descend until I crossed over the CUN VOR. If I recall correctly, the program approved me via the ILS approach via the CUN transition. In this situation, is it typical to fly to the CUN VOR at cruising altitude, then just start my decent to the ILS approach? If I recall correctly, I was not vectored in at all after crossing over CUN. If an easy way to avoid this is to just make sure a STAR is included in my flight plan, that is fine, but if this is a typical process, I would love to understand how it works. Let me know if any clarity is needed. If this is also just a limitation with Pilot2ATC and I would typically be handed off from center to arrivals and assigned an appropriate STAR at that time, let me know, this is just something I have never experienced before. 

 

Attached is a screenshot of the actual flight routing that was generated.

 There are other options for the selected route in SImbrief, just pick one with a STAR.
