HX DataSynch Alert after FW update THEN GPS trouble

After updating tonight UK time to 1.658.2535 the unit installed and turned off as normal. When I turned back on I had a message about HX datasynch. I can’t remember what it said exactly but it was a problem message. Came out the menu and turned off. When I rebooted I didn’t see it again. Is this something to be concerned about?

    Update: This could be a coincidence, but this morning i had the first ever GPS fail of my K3. First ride after FW update. Rode for about an hour and all was fine. Then looked down, whilst moving, to see zero speed (without an auto-pause). Distance stopped. Sensor readings (HR, PM, Di2) all connected and moved up/down as expected. Map froze to where the GPS went out. This is Central London, so i don't expect it to be a bad coverage zone (if such a thing even exist!).

    Turned it off / on and went for a test ride an hour later - and all was fine. Then another 5 min ride just said "acquiring GPS" for the time. Another off / reboot and another ride had GPS straight away. This is odd.

    Thoughts?

    Another ride, another GPS fail after 1h. Saved the ride and rebooted and it picked up the signal immediately, but what a faff.

    Same problem with me. Karoo 3 lost gps signal 10km before home and didn't reconnect back. Never happened before.

    Hi, I've also experienced the issue with the lost GPS fix after updating to the new version 1.658.2535.20. While driving, this can usually only be fixed by restarting the KAROO. I contacted the support team today. Let's see what comes of it.

    Updated to 1.658.2535.20 this morning and the unit messaged that it couldn't acquire a GPS signal.  Locked up and couldn't track route. Numerous restarts during ride - failing numerous times -  it logged just 47 of 54 miles. Pretty pathetic update testing!

    Today I tried to replicate the GPS failure I had with the Karoo. Same route—mountains, forest, and open terrain (Gravel Tour)—covering a little over 100 km. Today, the Karoo worked flawlessly, with no errors or outages.
    Strange—maybe there were problems with the satellites yesterday 🥳

    I’m guessing / hoping that support will spend their Monday morning seeing the issue persists as reported on this forum- then hopefully the software engineers will either fix properly or roll back to previous whilst they figure it out.

    Yesterday I received another reply from the support team ..-

    Hello,

    We have received multiple reports of GPS-related issues, and our developers were notified late yesterday of a potential issue. Thank you for your report and for bringing this issue to our attention!

    The team put a fix in place a short while ago that should resolve the issue. Changes will take place the next time the device boots with an internet connection (Wi-Fi or Companion App/smartphone) so it can check in with our servers. If your device is powered on, it needs to be powered off and back on.

    Sorry for any inconvenience! Please let us know if you continue to have issues. Replies may be delayed since normal business hours are Monday-Friday.

    Best,
    Jami

    From various comments on this forum, this emergency fix does not appear to have worked consistently for all. I just did a 45 min ride and GPS was fine.

    They may simply have updated the radio firmware. Current version: 1.2.20 ???

    After everything had gone smoothly yesterday, I lost the GPS signal again today over a short distance. Restarting the device sorted the problem straight away. Let’s see if there’s a new firmware update coming soon.
