After a update the equipment is blocked. iI have done everything that the video shows on the artuicles to make a reset , but after the white text on black screen appears, when i press the on/off button 3 times, i dont get a "cog" spinning!! and the screen returns to a picture of a tomtom connected to a computer, but with a red cross, as if its saying do not conect!!
