    Just did the test flight on my newly installed gps175. I am using a king ki-525a HSI. The unit was able to track the gps course perfect. I loaded an approach and it said approach arm and instantly went into approach mode. I armed the approach about 15 miles before the fix. It prompted me to turn to the final approach course and followed that perfectly. The glide slope on the hSI came alive but the autopilot never said gs arm. It stayed in alt mode and flew through the glide slope. The indication on the hSI was correct. Did I not arm it correctly or is there an issue with the install?

    Thanks
