AVweb’s Mike Busch has added a paragraph to his review of the Garmin 530, specifically outlining the things we’re missing in the 430 (but didn’t know it). Actually, with 2 of the 430 units in the C configuration, we’re not missing much at all.
The article is otherwise unchanged from last week, so you have to look for the new paragraph. It’s near the end, and is headed Smaller Siblings: Garmin’s 400-Series
The entire report is at Big-Screen IFR: Garmin’s GNS 530.
IMHO, it’s a Must Read, esp. for those who have yet to meet their 430 face to face.
