Ryan ORL Posted January 20, 2023 Report Posted January 20, 2023 I have a GNS 480 for sale. I recently removed it from my 1984 J for upgrade to a new G3X Touch panel. See my panel upgrade thread here: At the time of removal, it worked but needed a new backup battery. Rather than sell it like that, I sent it to Chris Short who replaced the battery, re-centered the COM carrier frequency, corrected a display-off current issue, repaired the outer knob encoder which sometimes was skipping, and replaced all the problematic capacitors. The unit now tests good and I received it back from him today. In all it was around $470 in repairs not including the basic diagnostic. I believe it's in good condition now. (Can send you a pdf of my email thread with Chris if you like) The display does have a cosmetic issue with delamination (see photos) but it has been that way since I bought my airplane and I have never noticed it in actual usage with the screen powered on. Also the rack apparently partly pinched/ripped away the serial number sticker but you can clearly see it on the photos of the unit config page. I have also the tray, backplate, GPS antenna, and a spare database card. I'm asking $3700, which is lower than I’ve listed it elsewhere (the GNS480 mailing list, for now). Figure $60 UPS Ground shipping, mainly on account of the insurance value. Obviously this is an expensive unit, so I am happy to phone call/FaceTime, send more photos, etc whatever you need to feel confident. I’ve recently sold a number of my other avionics on here and probably those members can vouch for me if needed. I can take PayPal or Venmo. Quote
