Hello,
I have a Kenwood DNX8220bt, which uses a Garmin navigation module. It uses SD cards for maps (official updates are named “Garmin KNA-SDxxe”), but I’m still using the factory installed map. I just read on this forum that some people have used OpenStreetMap maps in Kenwood navigation systems. I have some questions regarding this.
-
Is the factory installed map maintained and does removing the SD card with the openstreetmap revert the navigation system to its original state? (there is a map selection option in the menus, is it even possible to select the map to be used?)
-
Can GPS logs be used to add data to OpenStreetMap (technically and legally)?
-
The SD card should be in FAT32. And from what I read, all maps are contained in one file (gmapsupp.img). Is there a way to get more data (apart from swapping cards)?
-
Is there TMC support (from the wiki it looks like a work in progress)?
Thanks!
Jörg
