Re: 430N loses time
I've seen that happen to mine, with the 430N, as well. I think when the power is off the GPS isn't being updated and the clock will eventually give up and stop ticking. When it has happened to mine the vehicle was off for a day or two. After starting and giving the GPS a chance to update, the clock reset to the current time. Don't know whether it is a quirk or just the way it operates.
