What is worth getting excited about is the ability to plug in V1,V12,V134,V7,V18 and having the box plug in all the waypoints and intersections on that route for you. Especially handy when you come in over the mountains into the SoCal basin and are given an ammendment that reads like that and each of those V-airways has doglegs in it. That has been one of my main qualms with the Garmin boxes, I came smoking into the basin on descent and was given one of those type of clearances to get into LGB with the route taking mybe 15 minutes to landing. I looked at the chart and figured there was no way to dial in over 20 waypoints, so a 530 and MX20, over $30k worth of gear was exactly as functional as a Kx170b that you can get on ebay for under $1000, because I had to treat it the same way, dial in each freq and cross ref with the SL-30. When I asked Garmin at SnF when they were planning on putting V-Airways into the database, the guy plainly said "We're not going to, if we did, how will we get people to buy the next generation of boxes". I'm pretty much boycotting Garmin for that.
