Anybody here with experience swapping GNS430 to IFD440?
Has anybody swapped a Garmin non-WAAS GNS430 out and an Avidyne IFD440 in lately? We did understand that advertised plug&play is only valid for swapping GNS430W out IFD440 in. What is necessary to swap from the non-WAAS, only pulling new coax cable and mount a WAAS GPS antenna, or is there anything else required, i.e. changing pins and fumbling electronics?
