There is no need to add overview to gmapsupp. It can be copied as a separate file to GPS with the same result. Or user can merge overview map and detailed maps to a single gmapsupp:<br>
mkgmap.jar --gmapsupp --index 1*.img overview.img<br>
<br>
The second version adds data from overview map into index search, which cause duplicated search results, see attached picture. I think both version will show duplicated cities when performing search near current position.<br>
<br>
I haven't checked thoroughly, but I have noticed a delay, when switching from detailed map to overview in GPS. I think single map with more levels could be faster.<br>
<br>
Summarizing: in my opinion this is not a proper way to create a map. If you add direct support for this procedure to mkgmap, you would give some kind of recommendation for it. And since it can be easily done without any changes to mkgmap, I would rather leave it as it is.<span class="HOEnZb"><font color="#888888"><br>
