Garmin 430/530WAAS GPS Data Card Case

Every 28 days I have to update the GPS database information for the dual Garmin 430 WAAS GPS installation in my airplane. I normally stick them in my pockets, take them home (no internet at the hangar) and download the new data onto them, then take them back to the hangar to reinstall them in the GPS units. A while back, I somehow broke the little tab that pops up to remove nad install them in the GPS. They are a proprietary data card, and can onlt be purchased thpugh Jeppeson Sanderson Aviatio
