Wrong time in iGO Nextgen

**rider** · 28th February 2021, 03:32 PM

Hi.
Since a few days suddenly the time ( in top right button ) is one hour later on my tablet.
After app launch the time is ok for say 10 / 20 sec but it looks like when it finds the gps fix, time jumps one hour later while Android time is correct.

I started GPS UP app and I see this :

15-07-2001 ?

In iGO settings > GPS info also shows the wrong GPS UTC time ( or not available ) and no GLONASS at all, outside under a clear sky :

GPS UP on my smartphone Android 10 ( next to the tablet ) :

So, that is ok.

No Android and app updates installed, automatic updates always disabled although sometimes when starting the tablet I see the little download arrow on top downloawding something ?
Maybe Google screwed up something again ? Had that a few times in the past after such a invisible update of something, no idea what.
But did not noticed that the last few days.

Does iGO Nextgen use GPS time or Android system time ?

Wrong time is not such a big problem but when I calculate a route of let's say 10 min after calculation that route will take 80 minutes.

What's happening ?
Is there a setting in sys.txt to use the system time maybe ?

I noticed the same problem a few days ago in my car Head Unit ( Android 6.0.1 - same iGO version ) yesterday but I checked today a few times
but everything seems to be fine suddenly.

Tablet Android 5.0.2

Spoiler: Nextgen version

Someone has the same problem ?

Perhaps something a\o somehow went wrong with Daylight saving time (DST)?

Have you tried with a GPS application other than GPS UP? (And after removing GPS UP!)

Hi all

Just a question : are you sure that it is not the infamous GPS bug (06/04/2019) ?

I have exactly the same issue one time on two with my S2...

Well, daylight saving time is March 27 - 28 so I don't think so ?
And that bug ?
Android system time stays correct, it only happens in iGO.
I deleted gps up already and installed again, no result and no other gps apps.
Besides, as I said, with gps up I never had problems until last week.

>> Androïd system time is given by network and phone connection...

>> GPS-time is given by the satellites and many old devices will never be updated for the new calculation mode used since 04/2019

But for that...

with gps up I never had problems until last week

... no explanation at all

**rider** · 28th February 2021, 11:52 PM

So correct me if I'm wrong, the time displayed in iGO is gps time, not android system time.
Why did I never had any problems since 2019 ?

**BIBUOT** · 28th February 2021, 11:55 PM

Yes for the first question

No idea for the second one.............. :-(

And, DST does not refer just to a date but to adding/subtracting one hour.

@ kwbs

I also ran GPS Reset COM - GPS Repair, Navigation & GPS info, nothing changed.

Spoiler: Reset COM

As you can see the GPS Time is correct.

But in iGO :

GPS UTC time is always 14.25.51. Time never changes.

I have also TomTom Go, Copilot and Magic Earth on this tablet, all of them give the right arrival time except iGO gives driving time + 1 hour.
