Respectfully, the problem with that scheme is that there are twenty other people trying to shop for panels and get the Garmin Reps attention, and they will work with any one ustomer as long as the customer keeps asking questions (becasue they are polite), so if you ask them to “give you a course”, you’re tying up a lot of resources others want to use as well…. That’s why they have the tent briefings…In the Garmin tent, they usually have several simulated panels. Find the one that closely matches what you have (or want) and any Garmin rep can give you a course on how to use it. very helpful.
