TomTom Satellite Navigation Faulty Joblot - N14644 & Unknown The bigger one powers on, you can tell the screen is on as you can slightly see the backlight but nothing appears. Its also very sticky even after cleaning with isopropyl. The small one powers on and seems to work but when tapping the screen it actually taps towards the right so makes it very hard to use. May be other issues with them, have not tested beyond what has been mentioned. Securely packaged with fast dispatch!
