Garmin GPS 100 AVD Wiring Details

[Klaus Dietrich <101613.3377@compuserve.com>]

Alan,
I have powered my unit only to external power (no auto pilot, external
warning tone, indicator etc).
Pin 14 would be 12 V + A/C power (via 3 A fuse)
Pin 15 would be ground

Hope this helps.
 If you need more info I can fax you the wiring diagramm or you can ask
Garmin in USA Fax + 1 913/ 397 0836, Bill Stone, they are very helpful.

All the best

Klaus
