NO MORE SUPPORT FOR MANY NAV2 (& NAV3) DEVICES

Posted this on another forum, but might be useful to some folks here as well ..

Talking to someone who knows a lot more than me about GPS and this "possible" problem... and he tells me that what TT are saying is probably a load of rubbish !!

Apparently the end of the epoch Week Number Rollover is exactly what it says ... it is a WEEK NUMBER rollover ... so the only devices that are affected are those that use/calculate "weeks" and utilise the "week number" index !!

As most SatNavs don't even use even date/day information but simply use "time" then they will NOT be affected !!

He sent me to this site to show me that he wasn't talking rubbish, and sure enough, down the bottom is this little crumb of information ..

https://www.gps-repeaters.com/blog/gps-week-number-rollover-april-6th-2019/

"This situation won’t affect a receiver’s ability to navigate and/or calculate precise time, but it has the potential to create week, month and year timestamps that are wildly wrong. Applications which rely on GPS data at that level may be seriously affected."

I have a strong feeling that April 6th will be a "non-event" for my GO700

It looks like it may be time for a change, my old One V3 is now unsupported and all the major roads in N Scotland - A9, A90, A96 - are undergoing major upgrading over the next few years. Amazon are currently offering a Garmin Drive 51LMT-S with lifetime EU maps and traffic for £79.99, less than I paid for my One V3 UK back in 2007 ish, only slightly more expensive than the cheap Chinese no name models and around £15 less than the cheapest UK map TT. I used to sell sat nav and always put Garmin & TT about level with TT just poking in front because of the user interface. TT have changed that for the worse and Garmin seem to have stayed pretty much the same so now, along with the lack of support for third party customisations, TT seems to have lost that edge. Buy Now button pressed so I will be hanging up my hat here and changing my favourite location to another part of these forums. Out of here

As a frustrated TomTom user, I bought a Garmin 770 Camper PND a couple of years ago. I bought the Camper so I could change the profile of the vehicle so that the routing would be more like I'm used to.

This is just a personal view, but I think that other TomTom users may well agree:

Routing: I have found, especially in rural Cornwall, that Garmin will not route as logically as TomTom, in fact, Garmin will take you off the main road via narrow side roads only to rejoin the original road a bit further on. I believe that TomTom's IQ Routes take into consideration time to wait at junctions whilst Garmin's TrafficTrends™ does not.

Traffic: TomTom's Traffic is much better than Inrix, which is the digital service that Garmin uses. Running a TomTom and Garmin together has shown me that TomTom is much better for traffic.

I think Garmin may allow you to load routes, but I don't know whether you can set itineraries.

Garmin does allow you to load POIs which you can see on the screen. The POI loading is a bit long winded especially if you want to group custom POIs such as speed camera POIs away from other custom POIs, although you do get used to the process. Whilst probably not too much of an issue to many people, I have found that Garmin can't handle diacritical marks (accents on characters) when searching custom POIs whilst TomTom can. Finally, I believe that you can load custom POIs onto modern TomToms via MyDrive but you can only use them for navigating to as they don't appear on the TomTom screen.

You have TomTom for Android, how does that cope with custom POIs loaded via MyDrive?

I'm not aware of any SatNav that now offers remote control.

TomTom GO for Android is just like their current range of devices... poor.
Very little POI support... you can drive to a POI but you can't displaying them all on the map or setup proximity warnings.
Basic itinerary support called "My Routes" which again is pretty weak.
There is a folder called itn but it doesn't appear to do anything if you pop itn files in it.
I can't understand why they couldn't have ported one of their fully featured and proven Navcores (say from the 940) to Android with a facelift.
It’s like reinventing the wheel but making it worse than the original.

As itineraries, a remote control, RDS-TMC and full POI support with warning distance etc are so important when I travel across Europe I'm going to buy a good second-hand 540, 740 or 940... problem sorted.
It comes with all the bells and whistles (plus more) that my GO 910 had and it's still a supported device having just received a new Navcore update so no WNRO bugs.
The menus have been updated graphically and look quite nice but it's basically all there so will be familiar to use.
All of current offerings from TomTom are a joke as it's all about flogging cheap units and not about selling a comprehensive well proven driving aids for serious drivers.

Playing around with my GO 910s yesterday I stumbled on a now obvious fix for these devices.
The WNRO causes an issue with the X10 devices and they are unable to update the GPS almanac and ephemeris data.
This causes the GO x10 models to struggle when locking onto GPS satellites especially when your vehicle start moving as the device has to blind scan for satellites... pretty much making the device useless.
Using TomTom home and installing the latest QuickGPSfix will sort the problem as it supersedes/replaces the GPS almanac and ephemeris data until the data expires.
Unfortunately you'll need to regularly keep the QuickGPSfix up-to-date if you want to keep your x10 usable.
This workaround might work for other units... let me know.
