[time-nuts] Slightly OT - Magellan Car navigation displays wrong time

[Glenn Little WB4UIV]

I do not think that is a jammer unless it was placed on my van.
Today the offset changed.
The minutes remained at 40 but the hours changed.
I have opened a ticket with Magellan about this.
I am not real happy with their products, the POI database was wrong 
right after an update and they will not release a tool to correct this.
This database is XML so tools do exist.
I am waiting for their reply to this ti\me decode issue before I start 
changing database entries.
It still navigates well and I have been able to change time zones so 
that the time is now only 10 minutes off.
I think that I set GMT offset to plus 5.5 hours where it should be - 5 
hours.
I do not know of a way to display day number on this device.
That may be a clue, if I can get it to display date.

Thanks for the information.
I will continue to pursue this with Magellan and let the group know 
their answer.
I might be a hardware failure in my unit, but, I do not think so.
