Dynon EFIS D-10 Magnetic heading

How many of you had success with setting Dynons D-10 magnetic heading?
And are you using the external magnetometer?

With the internal magnetometer Dynon uses some very complicated math
to compensate for the magnetic dip, etc. Apparently the internal unit
does not work wery well and there is an optional external magnetometer
unit that works better. I really don't like to spend the extra money
and more weight in light of initial claims.

But there is really a simple solution I wish they would implement.
I sent an email some time ago reqesting they put in
simple DG emulation. I don't mind resetting it each time I start
and it would be much more accurate than the + - 2 to 5 degrees they
get with current setup. But apparently they do not want to
have such non sophisticated solutions.

If you have a D-10, how about contacting Dynon and requesting
they update the software to include simple DG emulation?
