Googling the group yielded little so here goes...
1979 172, overall average condition with mostly original radios and wiring (one RT-385 recently replaced by a TKM radio, M1 Loran from a few centuries ago) The Cessna 300 ADF has gone flaky. The box tests fine on the bench which suggests a wild goose chase may be in store to find the gremlins. One of the two ILS approaches at my home field require ADF, and a few fields I go to are ADF/GPS-only so I need one of the two. My idea is to find a good used Apollo GX-50/GX-60 unit and replace the ADF. No need to touch the Loran, it makes a good backup. I'll get legal ADF and DME capability not to mention a moving map. Trying to convince 4 other partners this is a good idea b/c it will make it easier to sell shares in the future and even if they are VFR-only the moving map is a big plus. The local flight school says they've been spending an average of $6000 to do this with their birds at the local shop. Those of you who've done this recently, any thoughts? Bet, -cwk. |

Gee whiz, Roy. Can't you tell the guy how much the installs cost your club?
Steve Robertson N4732J Roy Smith wrote: snip The GX-50/60 series are perfectly reasonable units, but don't forget to factor in the cost of maintaining the IFR database. Also, to be IFR legal, they need to have this funky external annunciator box mounted somewhere within the pilot's normal scan, which means you need to find a place in the panel to mount it. I don't know how much a GX-60 will add to the value of the plane. True, it is an IFR approach certified GPS, but it's also a generation out of date and doesn't have much sex appeal anymore.

My club has put in a mix of CNX-80's and GX-50/60's. The CNX is a much more expensive unit, but it's also a much better box. I guess it all depends on how deep your wallet is. |

I don't fly IFR but I think I'd consider getting the plane instrument
certified with the least expensive older unit I could find and then actually fly with one of the new portables such as Garmin GPS296. |

Or $12k for the 530. The 480 may be the way to go if you think WAAS &
terrain are important. But these options sound like budget busters. Thx, {|;-) Victor J. (Jim) Osborne, Jr. |

I do fly IFR and would like an approach-cert GPS, but I can't convince my partners. I make do with a Garmin 196, and I have to admit, the difference in capability of the airplane vs. having an approach-cert unit is very slight. Having something mounted in the panel vs. yoke mount would be nice. I think the 296 has approaches. At least they're long runway extension lines that could be used for a straight-in approach. But not certified, I'm sure. |

True, it is an IFR approach certified GPS, but it's also a generation out of date and doesn't have much sex appeal anymore. A basic 1979 C-172 is not a vehicle for sex appeal. I want no-frills utility. A 172 with an IFR GPS is a much more marketable beast than one without, regardless of the GPS in question. My club has put in a mix of CNX-80's and GX-50/60's. The CNX is a much more expensive unit, but it's also a much better box. Would you put a 12k GPS install into a plane with a 172 with a 40k-ish hull value? By the time you're done we're talking about nearly the cost of an engine overhaul, which at 1800 tach hours may not be far off. That will add a lot more back to the value, too. You can buy an engine for the next guy but the avionics are for the current owner. I guess it all depends on how deep your wallet is. Figure somewhere between mud-puddle and pothole. Quite frankly I might just end up repairing that damn fool ADF for just that reason. -cwk. |

No, no, no.... You DON'T want to try to repair that ADF.
We went that route for close to two years in our Archer, trying to repair the Narco ADF and Navs/Coms. We just threw good money after bad. We probably ended up sinking $2000 over a 2 year period before finally giving in and going for a Garmin 430 and new King Nav/Com. It cost a pretty penny (about $12000) but sure is nice now!
