Axel,
Welcome to the forum! Sorry that it took us 24 hours to get to your post. It's been a busy week. We also apologize that this situation seems to have frustrated you so much.
I think it would help to realize that the HSI on SkyView and the Map are really independent things.
HSI:
This displays a CDI to a selected source. This can be the internal SkyView GPS, or any external GPS or NAV radio you have connected. The CDI works like a standard mechanical CDI, showing a selected course, as well as a lateral deviation from that course.
The HSI can also display two bearing pointers. Again, these are selected by source, internal GPS, external GPS, or external NAV radio. These always point direct to the station. In a GPS this is your next waypoint, and in a NAV this is the ground station you are tuned to.
Note that the HSI doesn't really care *what* it is tuned to. You don't select the airport, waypoint, or VOR with the HSI. It's exactly like a mechanical device. You just flip the switch, tell it to display whatever the NAV or GPS, and it displays exactly what the connected navigation device tells it to.
The HSI doesn't understand a bearing pointer to a sub-device. You can't say GPS1:KPAE. This would require the HSI to somehow program the GPS to a specific waypoint. The HSI doesn't program the GPS, the GPS sends data to the HSI.
If you hook to an external or internal GPS you get the same identical capabilities. You can display the CDI or bearing to the flight plan on that GPS.
Bearing pointers and your course are only the same when you are on-course with a GPS. If you are off-course then they are pointing different.
SkyView Internal GPS:
This is where you program the flight plan, look up waypoints, etc. This has an output to the HSI, but it's exactly like it was an external GPS, where it has only one output, and that output is to your flight plan.
The huge advantage of a GPS is that it is a MAP, not just a needle. You can see the whole world on there, you can see everything around you, and you can look up information. All you have to do is look at the screen to see you are abeam the chicken farm. In the old days, the only way you knew was if the chicken farm had a VOR transmitter, and the needle pointed at it. Now all you have to do is look.
The GPS in SkyView also has a pointer/cursor. You can move the joystick, and select something. It will tell you exactly how far away it is, and on what bearing. Doing this doesn't mess with your primary navigation at all.
As far as we know, this is flat out the way it is done. You can't get a certified Garmin GTN to send out two bearings, one from your flight plan, and one to some other waypoint. A G1000 won't do this. No experimental EFIS will do this. No handheld GPS will do this. The idea of a GPS having multiple outputs to different points on the earth all while labeled GPS1 just isn't done. There might be some FMS units in the world that will do this, but those are whole different beasts than a GA moving map.
In many cases, Dynon does attempt to be industry standard, and a GPS that sends out both a flight plan and a bearing to a point not on the flight plan at all is really non-standard.
So, in a sense, bearing pointers are a bit outdated in a GPS only system. They are a holdover from the days when all your navigation source is give you was a line, and you needed at least two to know where you were. This is of course why we allow them to be turned off.
Future:
This is not a design error. The system is working exactly as designed. That doesn't mean we can't add this as a feature.
As far as I am aware, you are the first person to ask for this. We can't consider a feature until we know someone would find it useful, so please do not act like we have been asked for this and have not done it. In this case, I don't quite understand the way it would be used. I see that you are in Panama, so maybe some navigation there is a bit different than the way I fly, which is mostly GPS flight plans, direct-to, and just watching the map to keep my situational awareness. So it would be very helpful if you could describe more fully how you would use this feature and how it would help you keep track of your position. Is there a reason the nearest, INFO, and pointer menus don't give you what you want?
Now, this would be far from a "finger snap." Somehow we would need a user interface to allow you to select more than one flight plan in SkyView. Then the HSI would need to understand that a GPS source had more than one source. And then some things I am sure I am forgetting. It's never as easy as you think.
If you could point us to a device that you know of that works the way you would like, that is always helpful for us to consider how it should be done.
