hi Kajoe, I tried this on my S100 and it is working, however if i switch to the normal screen to adjust audio settings or play an mp3 file I can't seem to get back to the navigation screen, it seems to be still running though as i get the spoken directions but hitting the navigarion button only gives a beep and does nothing, restarting the unit and it's working again. Same thing happens when i put my car in reverse (rear camera comes on), after that I'm back in the startup screen with the icons... Can you tell me how to fix this?
