From what I read in the ublox manual and how this receiver behaves, it is a M8M and not an M8N. Also there is no "EXT CORE 2.01" message on boot which would be expected from an M8N but not an M8M. The difference is that the M8M version does not have nonvolatile flash memory to store the configuration. The receiver only stores settings in On-chip BBR (battery backed RAM) which lasts as long as the installed battery, certainly not over night if switched off. Although the systems runs very nicely, I can only give two stars for quality with this seemingly being not the product announced.

Session This is a key comment. I believe my backup battery has died (reads 0.0 volts off the tiny coin cell), and as a result every lock is a cold start. Under cloudy skies this can take many minutes.Thank you for the explanation.
