Lost marks

[charlesbulleid]

Hi all using the tz map app I uploaded a large file containing heaps of marks that took up the entirety of limit of marks using the wifi connection it uploaded all the spots fine but then my previous marks already on the tz2 which I had marked on there disappeared are they still on the sd card or gone forever?

Thanks in advance for any ideas or help

Waypoints and routes do not automatically back up except to the cloud and then any changes to that set would be overwriting the old set. The microSD card of the TZT2 only is for Mapping and PBG storage (using the DFF3D). It is not possible to save points to that card. Points are saved to the USB, normally to a connected Jump drive. This is done at operator convenience, not automatically. If you have prior saves of points to a USB stick, they can be restored from there.
