We removed the existing GMX200 and GNS480 and installed a new metal custom fabricated panel, all new push pull circuit breakers, G500 with Synthetic Vision, GTN750, GDL88D, and JPI EDM930 primary engine monitor. We also sent out the electroluminescent subpanels for refurbishment where the white lettering is brighter and the backlighting is a little brighter at night. We can make any older Bonanza panel look this good!
