At Aviation Consumer, our job is to sift through marketing hype and conduct impartial evaluations of products and services. Sometimes this includes products that aren’t yet to market, creating uncertainty regarding the product’s future. That was the case nearly a year ago when we covered Avidyne’s IFD540 and IFD440 GPS navigators (September 2012).

We recommended the IFD series as an easy way to modernize a stack of aged Garmin GNS navigators. The major attraction is the IFDs plug-and-play design, which slides into a Garmin GNS530W and GNS430W installation. Avidyne said the larger IFD540 would be available later last year, while the smaller IFD440 was supposed to be delivered earlier this year.
