Just started today.
Zumo390. When I use it in the car it keeps going to USB mode (with a picture of a PC) and then shutting down a minute or so later. When I restart it the same thing happens again after a few minutes.
Any ideas?
NB I am using the official Garmin USB power lead.
 
my 550 used to do this , clean all the terminals , reseat all connections ,update it , take out the battery ? if you can , do a reset , then see what happens .
 
Its up to date have reset it. Will see what happens tomorrow.
