For Horizon's 7.4 AT Users FYI - Keep Firmware Version 5.001

Running
1

Hello,

I own a Horizon 7.4 AT, HRM with Apple TV for running. For about two years, no issues. However, I updated to firmware to V6.001 and suddenly my Bluetooth did not want to connect, both phone and Apple TV. At the time, I was not aware it was a firmware issue and both Horizon and Zwift were troubleshooting the problem vigorously, as so was I. Weeks later and today, Horizon found the problem in their latest firmware with Bluetooth and send me the old 5.001 version. I rolled-back my treadmill to the 5.001 version and problem solved! I am sure Horizon will fix the issue with later firmware, but I would keep the old 5.001 till then.

I didn’t even know you could update. Mine is working fine. If it isn’t broken, don’t try to fix it.
But thanks for the info, I definitely won’t touch it.

Hello. I have the same issue, but they are saying they don’t have the V5.001 version. I have a 7.4AT-02. What would be the possibility of you still having that file on a USB?
