Powers on and is detected via Qwiic. PPS LED does not come on and no UBX/NMEA messages.
U-Center same. Tried resetting same result. It was working just fine, stopped to replace SD card and did not come up. It has a lot of uptime may be some module internal failure. Guess I’ll get a new one and proceed.

Did you purchase it within the last 30 days by chance?
No, more than a 1 year ago

with U-Center I was able to Poll with MON-VER, It was 4.04 . Tried to update firmware and exits with ‘Exit Code (2)’

Drats - we have a 30-day warranty on all products, and some have up to 1-year for certain items (mostly the more expensive stuff, RTK devices, etc)
It does sound like the module died 
Hi @dk23 ,
If you can communicate with the GNSS using u-center, then it should be possible to reload the firmware if needed. The latest firmware (4.04) is available on the u-blox website - in the “Firmware Update” tab. In the u-center Tools \ Firmware Update utility, select the .bin firmware image and try first with the defaults. Click “Go” to start the update. If it fails, try again with permutations and combinations of “Enter safeboot before update”, “Send training sequence” and “Use chip erase”.
I hope this helps,
Paul
