Bootloader

Remember all you need on the SD card is the new map folder & a copy of your ttgo.bif file from the unit, ensure the navcore is patched & the map is activated then you "should" just be able to insert the card then go to manage maps/switch maps.

"Didn't work" ?? Tell us more, map version?/navcore patched?/map activated? (...map.dct file inside the map folder)/what does/doesn't happen?
