Subject: 540 doesn't sequence during SID

OK so here's my question then. If you need baro corrected altitude to the 540 in order to automatically sequence waypoints, is there a way to get that besides having an Aspen or G600? An air data computer like the Sandia will still only provide uncorrected altitude because there is no way to set the local altimeter setting into the ADC. It would be no different than a regular encoder. Unless the 540 has a place to enter an altimeter setting so it could calculate it's own corrected altitude based on external uncorrected information. The reason this is so important is that you cannot manually sequence the waypoints unless there is a prompt from the 540. For example, if I highlight the CLIMB TO 1200' waypoint (see pic above) THERE IS NO LSK FOR ACTIVATING LEG OR MANUALLY SEQUENCING TO THAT WAYPOINT. I just tried it on the simulator and same in the real airplane. And in my experience, the 540 does not alway prompt me to sequence. It happened once on a SID from KTRK, but not on a MA or the SID from KLVK. So if the 540 doesn't prompt you, then you're screwed. You have no guidance and there is nothing you can do until you get to a point where you can go direct to a waypoint in the flight plan, not an intercept heading. AviJake, who can I talk to today about this? Is there someone at Avidyne that is familiar? I need a solution fast. Hard to believe this situation exists, unless I am missing something.
