I know many of you won't believe me, but I recently installed a GPS 175 in my plane, and the system ID that I noted while it was powered from my benchtop power supply was different from the one that is now showing after install. Of course I redeemed my database coupon against the old system ID so now all of my databases are invalid. I have reached out to Garmin support to hopefully get credit for the updates that should come with the unit.
Anyway this is a warning to make sure you note your system ID *after* you've fully installed the unit. Maybe this has something to do with the configuration module?
