Cyclecomputer and GPS Owner's Manual Database

Spoke Divider

Using the database

The large table on this page has links to user instructions for most cyclecomputer and GPS models.

This list includes GPS units including wristwatches which do not map routes, but have bicycling-specific features (cadence-sensor pairing, swim/cycle/run selection for triathlon use).

We have worked hard to make this list complete, but information on some older models is unavailable; also, new models appear from time to time. Only the major manufacturers tend to place owner's manuals online. If you have information on a model that we don't list, please send it and we'll post it.

Many bicycle computers are rebranded. Look for similarities in appearance and function when trying instructions for a computer not on our list. A Web search on the make and model, plus "manual" or "instructions" sometimes turns up information posted by an owner. Old versions of manufacturers' Web sites preserved on the Internet Archive may list older models. Our contact information is at the bottom of this page. Sunding SD-546CIf you can provide information, or correct an error, please do.

Here is one style of cycle computer which is sold under so many brand names that we quit trying to list them all. They are rebranded Sunding.

A through F, and GPS, in the right-hand column of the table below link to an article giving the dimension which the computer uses to measure distance:

Whew. So many models.

World Instructions in additional languages, and video instructions for some models, are on the Sigma Web site; search on model name here. Sigma changes filenames for manuals, so look on the table of contents page if a link has broken.

Model names are given in numerical rather than alphabetical order here, as model names for different computers can be similar. If in doubt, check the picture of the computer on the Sigma site.

If an early Sigma computer has no setting for miles, use the setting for kilometers/1.609344 and the reading will be in miles.
