Any opinions here? I like the avidyne but my shop, which is a dealer for both, warns me against it. They say that they have yet to install one, which may be a function of the ability to buy direct and do an easy install, and concerns about the company's sustainability in the future. I have a 430w so any upgrade is going to involve some construction so that's a wash. I like the "fms like" features of the avidyne, the keyboard, and the option to not use the touchscreen. Auto fill of nearby fixed and display of the comm facility are pretty slick too. I think that the resale market might favor the Garmin, and I too wonder about Avidyne staying in business over the long term.
