Nevermind my previous question about closing Skinbedder on RR exit. I set it up in my car and it's a non-issue.
For me, it looks like IG3 with RPM's skin and b8bboi's IGmon is the final nav solution. Everything works beautifully together. The only additional features that could possibly improve the current setup is hideable buttons on RPM's skin and a functional next turn box in IGMon.
For anyone who's interested here are the form position settings I used in IG3.ini in RPM's skin to get IG3 to properly embed in b8bboi's blue 800x600 CFX skin:
;This is the initail position of the form.
;This is the initial "usable" Width & Height of the form.
