MIO Cyclo 505HC - Cycling Navigation Review

MIO Cyclo 505HC – Cycling Navigation Review

There is an issue with the latest version of Windows and how it work with MIO CYCLO products. I assume it equally affects MAGELLAN users too.

You need to open CYCLOAGENT and upgrade to v2.2.13.1 – or later.

Attach your cyclo unit.

If there is an upgrade tot he firmware; do the upgrade.

If there is no connection available (this is the bug) then you need to perform the exact same firmware update on a PC with an older windows version.


But annoying.

Like many, I had the issue with my C505 not being recognized after the Creator update.

I rolled the update back, and installed the latest version of Cyclo Agent. Was able to update my 505. One problem, though. Although the software did update, the OS image did not. Still unable to get my Cyclo to show the OS image version necessary to be recognized by Win10 Creators.

I went through all the necessary steps properly, twice.

The Cyclo is a decent unit, but what it boils down to with any cycling GPS is post sale support. Support for the Cyclo units is just about useless. Very, very infrequent and sporadic updates, if at all. I totally recommend buying a unit that has better factory support. My Garmin isn’t perfect, but at least there is some semblance of support over the long term, and an online community / user base about 100 times as large as the Cyclo base…so help is much easier to obtain when needed.

Thumbs down on the 505 due to very weak support.


HOLY COW. I think they’ve fixed the issue. Someone at Magellan still cares. Amazing. My Fenix started acting wonky, I think the battery is shot. I powered up the Cyclo just for the heck of it, and an update was waiting. Installed it, can see the device on my Win 10 PC. Woo hoo. There is hope. Figured I owed it to Magellan to post this, as I haven’t exactly been a cheerleader for them in the past.
