    Is there a way to downgrade to a usable firmware version ? Given the  GPS issues, watch is quite useless for me right now (only half tracks are recorded of  an 1 hour run, because gps sync takes so long) 

    Try this solution from another thread here: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-45-series/244927/waiting-for-gps-for-to-long. It worked for me.

    This didn't work for me :-( thanks for the pointer anyway

    Sorry it didn't work. There seem to be so many different problems, or at least symptoms, it's hard to know which watches are affected or under what circumstances. I've sent you a PM.

    When does this ballast upgrade?

     No worries, I'm using same approach as with last watch. I start tracking a run with the watch stationary at a window while changing onto running gear. Then I discard it and track the real thing..

    I can see that Garmin removed my comment, so let me post it again. After my FR45 started displaying "CPE: Missing" and GPS working terribly slow and inaccurate, my watch was replaced by Garmin. My happiness lasted only couple of days during which the CPE status displayed "Current". Sadly, as of last Saturday it shows "CPE: Expired". Tried syncing, restarting, etc. One thing I did not try is to connect the watch to Garmin Express because I do not have access to a Windows machine. But again, since November 2019 the watch has been working just fine without the need of Garmin Express sync. It is most probably the latest 3.90 firmware that has fundamental bugs and causes this misery. Luckily, I will be getting a refund from Amazon and will probably switch to Polar. It is a shame as this was a really decent watch for an amateur runner, as long as it worked.

    When will the next upgrade take place?

    My journey with FR45 has come to an end, just received a full refund from Amazon. Such a shame as this has been actually a great watch until 3.90 release. I just can't imagine how Garmin could have released an untested software. Having spoken to their support couple of times I am sure they are well aware about the issues with 3.90 version but who knows if they ever try to fix it. Actually, one of the support agent I was on the phone with suggested himself getting a refund from Amazon as the watch is probably "unfixable". Good luck to others struggling with GPS accuracy, I hope you will get your refunds soon.
