Okay, so no matter what, I always need to enter Cartouche after tracking a route, to make it 'stick' on the server?
Is it sufficient to just login an select 'update map'?
No. The roads you record have no information in them. All waze knows is that they are drivable. You would need to add street name, directionality, specify type of road.
Because I have recorderd numerous new roads, but haven't gotten to editing all of them yet
Quick find your new roads by using the unknown roads
layer. Turn off all the other layers and just look for the bright red lines. Those are the unedited roads. Turn on the appropriate layers to help you identify and label your new roads.
I sometime see little bits of road, probably because someones GPS is 'off-track', that seem to have been made 'stick', but I cannot imagine that someone edited those.
If you have driven over them, you can fix them. If the fix is beyond your current skill, switch to live map at that area and report a problem. Other local wazers or your area manager can help you out.
