How much should I budget to have a Garmin GTN-650 and GTX-345 (w/ADS-B in/out, no wass) installed in a piper archer? I would like to include GPSS to Century 21 and flightstream 210 for Foreflight integration of flight plan. I would have DME, KX155 and old transponder removed. I'm guessing $17K for HW alone plus install cost. Would this allow provide synthetic vision to foreflight for back-up AHRS? Any recommendations for avionics shops around New England area?
Thanks
