For those with a GTX 330 (and a compliant WAAS GPS), Garmin provided a simple (i.e. no new boxes and minimal if any rewiring) ADS-B Out path with the GTX-330ES. I believe that many of us have a compliant GPS (e.g., a GNS 430W), but a GTX 327. How about a slide-in GTX 327 replacement with an easily accessible (if that's possible) extra connection for the GPS signal (rather than using an existing multipin connection, which would be tough to wire into)? Other than that GPS connection, no other changes would be needed (no additional boxes or extra antennas). Am I missing a reason this wouldn't work? I tried to "sell" it to Garmin some time ago, but I couldn't generate any interest. Perhaps someone else?
