I just finished my LPC in the sim last night at CAE NJ. The Garmin is the main nav system used in the 76C+/++ these days from what ive experienced.
Unfortuately the sim does have a few gremlins.
EN48, PM me a email address and i'll give you more info from a customer point of view.
also, Thanks to all the instructors at CAE. Great bunch of guys there, and the front desk staff are great too.
ps don't forget the free afternoon warm cookies when youre there.
