I am not sure if anyone will know the answer but I figured why not. I am currently considering an upgrade to my M20C, either a Bravo or an Acclaim. With the Bravo, I will probably do a complete panel overhaul. installing G500txi, 750, 650, ect.. I am just wondering if anyone would know the rough cost of the Nxi upgrade? what would it be, $50,000? maybe more, maybe less? just outweighing the costs and seeing all options. Thank you for the help.
