I have just installed a D100/D120 with Garmin SL30 Navco and 328 transponder. everything seems to be working fine after a couple of simple snags where ironed out. I have had the SL30 tested and the VOR Nav side is working but nothing seems to display on the D100 I get a compass display but no HSI display. Am I missing something simple
Thanks in advance
Pete
