Map street names randomly missing during activity.

Hi all,

This issue has been valid over several Topo map updates and firmware revisions. Attached is a very poor image grab of my "Walk" activity from an hour ago.

Note how the street names are randomly missing. As the map scrolls during an activity, some names appear whilst others don't. This is not in any way consistent. Sometimes when I follow the same course, a different street name may appear where one that was there yesterday will not...... When navigating to a point, the turn-by-turn is showing the street names so the database is fine. It just will not display them. My zoom is set to 120m. If I go to a higher zoom level, it gets cluttered by point icons (like bus stops, shopping, car parks ,etc) and the icons don't seem to be affected. Just the street names....

Now, I have the Garmin Topo V6 Aus/NZ map on the watch however it does the exact same thing when doing a hard reset/rebuild using the supplied TopoActive maps (it is at the most current map).

My guess is that the CPU is not prioritising the street names during an activity hence randomly it just doesn't display them.

Firmware is current, maps are current and I have no 3rd party apps, widgets or watch faces installed.

Can anyone confirm if they have the same issue?

    I think there is more to this that is causing high CPU usage during map display.

    My watch was fully charged on Sunday evening and I did around 3.5 hours of "Walk" activity with the occasional map view but mostly on the heartrate view. This included 30 minutes with full navigation (direction indication and buzzer). On Thursday morning the battery was at 53% which is quite acceptable for me as I charge the watch every Sunday.

    Yesterday (Friday) I did a 1 hour 27 minute walk on map display only. When I finished, the battery was at 23%. Whilst I understand that map view will take more CPU resources for drawing, I think the drain is a bit too high. Perhaps there is a code issue which is causing the street names not to be drawn with associated high CPU usage?

    Well, sadly it appears that Garmin has abandoned the D2 Delta as even support can't assist with this issue. Oh well, at least it works...... sort of.

    I have seen random bursts of higher than normal battery drain on my D2D also. So far I've been unable to isolate it and Aviation Support hasn't been able to replicate it.

    Regarding the street names, I will try and test your issue on my D2D in the next day or so.

    Thanks @drobert. It is definitely a high CPU load issue. I noticed last time that ALL the street names were missing when I started the Walk app before the GPS sync was complete. Once I got the green arc / buzz, the street names appeared. The main issue seems to be as the map is moving (redraw). Coinciding with some unexpected battery drain on map view (certainly much higher than I remember it used to be several firmware revisions ago) i'd bet on a CPU runaway condition in the code.

    @drobert, do you regularly force a WiFi sync? I have had many instances with my partner's 5S running completely empty overnight that I have been able to resolve by manually forcing a WiFi sync every 2 or 3 days. It just seems like an automatic update check sometimes fails to connect with a Garmin server and causes the watch to go into a check loop until the battery is depleted. I don't notice this on my D2 Delta as I generally do daily syncs after an activity.

    I tried to replicate this but the street names in my part of Canada always showed up, though they were sometimes delayed in rendering when zooming in/out or panning. Do you have any kind of process to replicate this or does it happen in all cases?
