I've re-bought another 520 Plus. I really like it now - maybe 3.0 firmware has improved it - re-routing seems to kick in sooner and works closely to what i imagine how it should from the one ride i had used it so far.

When it's set to cycling with all the proper avoidances (tolls, ferries.....) - it will route via the nearest bike paths rather than road - pretty nifty.

Oh - and the color screen is truly the best i've seen. When i first took it out i thought Oh crap did i left the back light on at 100%....No - my back light was at zero but the screen was just so bright and clear in good daylight - a real joy to look at. Unlike the screen on the cyclo 505 which was pretty dim even in the brightest daylight.

Navigation on the map screen is fantastic - lots of useful info - like it tells you what course or bike path you're on......and of course i love the bright white directional arrows - super clear which direction to follow.

The Aussie color map does provide some additional info - like you can see marshlands, waterways - fields/parks....etc.

This is a keeper for me.
