62 screen doesn't help to see if map tiles exceed the limit in astro or to see if there are other problems with this map.
do you have a basemap in astro?
I think it's the standard base map and I have tried enabling and disabling it
Basemap cant be disabled.
in the unit there is a list of maps, the two that show up are base map and UK. You click on the desired map to enable or not. Is this right.?
On clicking about I have the usual trade mark info but it doesn't mention maps. If I go to maps it says- Enabled-worldwide DEM Basemap,NR.
I will connect and look in the internal files.
Have you tried another small map?
One of the free ones.
I have been reading about this model and you can give the maps any name you want.
Do you have on your SD card this layout?
In that folder a file called gmapsupp.img
You can give it any name you like with you unit.
What do you see when you go to from the manual:
Are there any maps to turn on or off???
