From: Quite near 'An aerodrome somewhere in England'

I've had to get one of the GNC250s repaired (input selector failed) and one of the GPS150s repaired (ENT key failed). But overall the reliability of our Garmin kit has been much higher than the failure rate of Bendix King KX155 NavCom, DME and ADF displays which seem to fail with monotonous and expensive regularity!

And as for the actual cost and usefulness of the ADF receivers....

We get the odd RAIM ALERT, but apart from that (and the end of epoch rollover nause a couple of years ago) the GPS performance has been superb.
