I have bought a 2200 USD D10A instead of 1600 USD GI-106 CDI. I wanted PRIMARILY a CDI. Not having remote compass, I would greatly appreciate having a simple CDI function, especially for flying ILS. Currently, my CDI/HSI during an ILS points anywhere but straight up. The same while flying direct to VOR. Yes, I can add a remote compass to improve ground track indication but it is an extra complexity.
