I want to replace the F500 stock maps with 2008.4 maps, POIs, and buildings. Everything has been downloaded and I'm ready to go.
Will I be mixing the new maps with the old maps or will I be overwriting the existing maps with the new ones? Or, do I need to remove the old maps when I add the new ones?
Or, can I keep the new maps on a SD card and not touch the existing maps?
