Amazing little gadget, I have no complaints other than the fact that sometimes the wrist gesture to wake it up sometimes lags or isnt very responsive. Amazing customer service as well, would buy again.

Love this Helmet

Nice tires. I don't understand why they named it Grifter.

Great product. Have nothing bad to say about it. Assemble easily with good instructions. Great price too.

I purchased the Garmin Edge 1050 primarily for bicycle navigation and route following. The unit originally came with working U.S. TopoActive maps. Garmin then offered a map update. The update failed with “Map Update Failed, Error Code: 0” and the original U.S. TopoActive maps were removed.

I connected the Edge to Garmin Express on Windows and attempted to reinstall only TopoActive United States East and West 2026.11. Garmin Express repeatedly failed with “Some Changes Not Applied.” The device has 42.1 GB free out of 57.6 GB, so lack of storage space is not the problem. Garmin Express now shows TopoActive (0), leaving the device without the U.S. TopoActive maps it originally had.

For a cycling computer costing over $600, this is shocking. A routine manufacturer-provided update took a functioning navigation device and removed the maps required for its primary purpose. This Edge 1050 is effectively useless to me as a bicycle navigation computer.

Hi Franklin, we're sorry to hear about the issues you've experienced with your Garmin Edge 1050. Your feedback is important, and we recommend reaching out directly to Garmin Support for assistance with the map update. We appreciate your patience and hope the problem can be resolved soon.
