nav122 parts OR what can I replace a nav122 with?
OK, my nav122 has died with a stupid mechanical failure in the
frequency-selection gear. Seriously, WTF was Narco thinking when they put plastic gears in such an expensive box? So, question the first: Does anybody make aftermarket replacement parts, or should I buy a dead unit and canibalize it? Question the second: If I choose not to fix it, what are good options for a replacement? Does anybody make a clever all-in-one gps or something that would fit in the same panel hole? -ed falk -- -Ed Falk, http://thespamdiaries.blogspot.com/ |

It's ocurred to me that a decent machinist could make a living just
making after-market replacement parts for this and other shoddily-built avionics. -- -Ed Falk, http://thespamdiaries.blogspot.com/ |

I've found their factory service to be quite reasonable. The only caveat is that they will go over the entire unit, bringing it up to the latest mods and doing a full factory acceptance test on it before they let it back out. The upside is that you get a 90 day warranty on the entire unit. From what I understand, whether it is worth it or not depends on the serial number, earlier ones used different boards and have more problems with connectors and what not, and may not be economically repairable. Mine is a "B" chassis, whose synthesizer board went bad. Narco fixed the synth card (replaced a ROM), repainted the face and needles, replaced gears that were cracked but had not failed altogether yet. There was something else they fixed too, but I can't recall what it was. The total charge was under $250 (this was 2 years ago this month). That was well worth it in my book, far less than the cost of any replacement, and less than I got for the NAV 11 on EBay that this unit replaced. Narco will do a flat-fee evaluation of your unit and call you with the cost to repair if you choose as well. The flat fee I think is 1 hour of shop time, which I think was $105. If you choose to repair, that fee is applied toward your repair. |

In all fairness, the NAV122 is a 20+ year old radio. I doubt Narco expected them to still be in service this far down the line. Nylon is lighter and far cheaper to make complex parts (gears) than machined aluminum. I certainly don't begrudge their choice to use nylon gears instead of aluminum. |

If you choose to repair, that fee is applied toward your repair. I've had both good and bad experiences with the narco factory. The most recent experience was bad. This was a year or two ago. Sent in my 122 in for a localizer problem. The NAV worked good. I asked for an estimate and they called me said that it would be $700.00 and the radio was already repaired. I asked them what cost $700, and they said that they replaced the whole gear mechanism and fixed the localizer problem. There wasn't a thing wrong with the gear assembly. I told them I wanted an estimate and why they didn't give me one. They didn't have an answer. I told them for that price I didn't want to get it repaired. They said that they wanted $700 and that was all. Then they said that I should give them %300 and they would remove all the pieces they put in and give me back a bucket of nav 122 parts back. I asked them WTF an estimate meant. They gave me no answer. They then said that everything left the shop 100@ and said that quality control was their driving factor. After a bunch of **** talk I gave them $700. *******s. Got the 122 back and it had the exact same problem. QC, Bull****. It was all money driven. Sent it back three times and the third time they again charged me $130 COD where I didn't have an option. I'll never send another radio back to their factory. I've always liked the Narco stuff and still do, but don't like the way they treat their customers. My next plane will have other stuff in it. Dave |

I don't know what your panel space requires, but consider a
reconditioned King KX125 - has a built-in CDI. Check trade a plane for reconditioned units from major advertisers, or check J.A. Air Center (northern IL); they frequently have reconditioned units. |

Think of it as having a back up CDI with radial identifier. Dave |

Narco gets hammered a lot here, but the tech manager I talked with was good and I enjoy the radios. -- Regards, Ross C-172F 180HP KSWI |
