I have been getting false terrain and obstacle warnings while landing RWY35R in KAUS. These happen under 500ft while on the ILS. Pretty annoying.
The warnings I get are similar to the ones described in this thread on another forum:
Garmin GPSmap 496 False Terrain Alert - AviationBanter
I currently have an email exchange with Garmin on this issue, but we haven't gotten anywhere yet.
Has anyone else had this problem with a 496 at Austin or any other airport?
