You may find eBay as your best source for used avionics.

Whatever you do, don't pay very much for ANY Narco radios.....

ebay had no at165 listed at all the last few days, and I am aware that narco went bust, but trying to prolong the agony begore I pay to rewire fora different unit. once again, are there any other units besides narco that will plug and play. thanks

Good luck on finding an AT165. I have been looking for one for over 7 weeks. Mine died and they are unrepairable. I have called several used avionics suppliers and still no luck. The last one that came available on e-bay lasted only minutes and it was almost the cost of a Garmin.

Garmin sells an adapter tray for their GTX-320A transponder to fit older King and Narco installations. This makes it "slide-in" compatible with your existing Narco AT50A. GTX-320A's can be found for around $1000 and will last.

I'd buy another worthless AT50A for cheap before I spent any real money on an AT165.

thanks for your responses, especially on the garmin tray adapter. RLM
