If upgrading a legacy G1000 to NXi, you are paying for faster processors and better screens. Rough Estimates: Hardware (displays) runs roughly $25k–$30k. Labor varies, as software configuration and testing incur shop hours. Compatibility: Check if GIA 63/63W units are compatible. This upgrade usually increases hull value significantly as it future-proofs the cockpit. Maybe make money on it in the long run??
