|
A friend of mine has sold his Garmin 430 because he got a good deal on a 430W.
He needs to change the GPS antenna and possibly its cable if it
doesn't match the new spec.
I looked through the manuals to see what differences there might be in
the pinouts. There are few and of little consequence. None are
connected in the certified installation in my Cessna 172.
I offer the list here in case anyone is interested.

Jeff,
Several years ago I had a 530 and a 430 upgraded to WAAS capability (530W & 430W). With the new capability came a pair of new antennas, new antenna cables and the admonition NOT to cut the cable length. The whole system was very finely tuned and to ensure the accuracy in positioning required for instrument work the new hardware must be used as provided. My Garmin units were in the instrument panel and the antenna installed on top of the panel so I had to carefully roll up the 15' of RG-400 cable for each unit so it would fit inside the instrument panel.
So, yes, he has to change the antenna and cable and ensure it all meets Garmin specs if he is to do it "by the book."

Robert,
Page 3-9 of the Garmin 400W Series Installation Manual 190-00356-02
discusses the minimum and maximum cable loss permissible, and how
connectors and cable length influence cable loss. I found no mention
of requirements to maintain a specific cable length.
With your GPS antenna on the glareshield, a direct connection would
definitely have been too short.
