6700 updated to SmartSDR v4.2.20 results in GPS no longer functional

K5SRT_Ross

2026-07-18 Updated 6700 to v4.2.20. Started with a factory reset following the latest recommended FLEX radio procedure. After install the FLEX GPS is not functional. "GPS is active" (see screen shot) but no longer populates with data. GPS antenna tests fine with professional GARMIN unit,10 satellites and 3D mode received. Any ideas of why moving to V4.2.20 cause the issue?

Have you tried rolling back to the previous version of SmartSDR to see if that corrects the problem?

Caution when rolling back!

Mr Radio, comments such as that require more details if you want to say something please.

If the GPS is not working on a 6700, then open a support ticket for the problem.

You can roll back safely, you just need to do a reset of the radio when you roll back.
