I have a magellan cyclo 505 experience.

Got the Edge 520 Plus and went for a 68km ride with the new Edge 520 plus. Route was mostly bicycle paths. The route was planned using RWGPS - tcx file format downloaded. When i deviated away from the route - the 520 took forever to recalculate......recalculate.....calculating.....and most of the time by the time it finalized the 'calculations' i was already back to the route. I heard the recalculations can take awhile but I didn't realise it basically meant the unit was unable to re-route properly in most real riding situations. Also it often failed in the end to produce any re-route options and just showed 'Off Course'.

Could it be that i was riding on bicycle paths? This is in melbourne - Scotchman's creek to the city and back.

It did do a successful re-route ONE TIME - when we nearly reached home and was riding the last few kms on road - and stopped at a shop away from the route, the 520 plus then re-routed successfully. The re-calculation worked quickly and a new re-reroute pointed me back to the planned route's direction.

I quite like the garmin map - they are much prettier....with landmark details (shops, folliage, grasslands) and the screen is mostly viewable in daylight with the back light zeroed. The 520 will also advertise what street name or trail name you are on.

The highlighted route on the garmin map (can't remember is it pink or purple) can be hard to identify if the light is not right or the zooming level too high.



The screen size is very functional - not too big and not too small. I am over 50 and used a bifocl sunglass (DUAEYEWEAR GLASSES) to read the screen.

One quite large advantage to the garmin - I like the garmin navigation cues - the garmin uses white arrows for turns are superior to chevrons (wahoo) and purple colored track (magellan cyclo). You can very quickly see what kind of turns you have to do. For the first time i was able to pick out the entrance to the path among some bushes. On the Cyclo i could not discern exactly where my turn should be.

i'll tell you now nothing navigates like the Magellan Cyclo 505 - you can go to hell and the Cyclo 505 will show you the way home (with super quick re-routing too if applicable). I had wanted a lighter gps than the Cyclo 505 (129grams).
