If you have a D10A, it is included in the D10A installation manual which is available from the Dynon Web site. Here is a direct link http://www.dynonavionics.com/downloads/100341%20-%20Rev%20B%20-%20EFIS-D10A%20Installation%20Guide.pdf
or just go to the Dynon home page and select "Documentation" for the unit you have (D10 or D10A), then click on the install manual link. Yes, it does connect through the remote compass module.
