I have a Dezl 770 LMT-D, for trucks. Last evening i recived a message on the device about a new update. I was very excited about it and i`ve installed it as soon as possible. And today, surprise! I input a new route, and in less than 10 seconds restarts COMPLETELY! Sometimes it does it every 1-2 seconds and sometimes every few minutes. I hope i am not the only one and please try to fix it. The sat-nav is 1 month old and i take good care of it. So i am pretty sure the problem is not from me.
