TomTom GO 620 fails to update large Europe maps

tomtom_un17

My Tomtom device has successfully updated the copy of Europe maps to both device and 32gb Sd card in the past. Now when I attempt to update or add larger maps the update fails. Smaller maps (France, Benelux, etc) can still be loaded but the larger maps go through the update process extremely slowly and fail after the device having restarted the download automatically several times. On several occasions the download progress has increased to around 45 percent and then started decreasing back down and then failing!

Hi YamFazMan, thanks for your reply, sorry for the delay in responding - I have been trying out the suggestions. The Usb cable route failed installing any maps other than GB and Ireland, continually getting part way through after hours of processing before aborting. I then tried the WiFi route, and it too took ages, but did complete the downloading to my 32Gb SD card. however, when I went into choose maps none of the maps on the SD card were shown. Going in to delete maps, the maps were there, and going back into choose maps, they were now available.

Thank again

Hi
@tomtom_un17
Welcome to the site....
The NAV5 (Wi-Fi) devices normally update using Wi-Fi....
If Wi-Fi is not available or is slow/unstable/unreliable.....
See Option... (2) Connect over USB....

TomTom Video... Updating your navigation device using Wi-Fi



If you have successfully connected your device to your Wi-Fi....
To check your Connection Speed, Signal Strength & Quality
On the Device... Tap 4Dot (.... Menu) --> Settings --> Wi-Fi
Tap on Your WI-FI name (The one Showing as connected)
A new Menu Page opens


On the left-hand side of the screen is your Wi-Fi Connection Status

Tomtom recommends a minimum Wi-Fi download speed of 30Mbps
Tomtom NAV5 (Wi-Fi) devices will only connect to a 2.4GHz Wi-Fi network
All the update actions are executed on the device...
___________________________

Option... (1) Connected Wi-Fi


Updating the device....
Tap the 4Dot(.... Menu) --> Setting --> Updates & New Items

Extra Maps are Installed/Maintained....
Tap the 4Dot(.... Menu) --> Setting --> Maps

I always update my devices one Update at a time
The NavCore Application and QuickFixGPS updates are force ticked by Tomtom... Deselect any other updates like Maps, Speed Cams etc... Update the mandatory item/s first, when complete update the remaining items one at a time

Note... NAV(5 Wi-Fi) devices connected over Wi-Fi do not require MyDrive Connect to be running Even if MyDrive is running you have no access the MyDrive Connect menu structures as used by the previous NAV3 & 4 devices
____________________________

Option... (2) Connected USB
If Wi-Fi is not available or is slow/unstable/unreliable.....
Tomtom recommends a minimum Wi-Fi download speed of 30Mbps

Connecting hard-wired over USB is normally more reliable than any Over The Air Connections
Updating your new device over USB will require "MyDrive Connect"
Get it here..... https://help.tomtom.com/hc/en-gb/articles/360013959499-Installing-MyDrive-Connect

There's no need to login to MyDrive Connect... See Note... (1)
Connect your Device to a USB Port on your PC
The Update will hopefully complete

If you're using a Laptop it would be also more advisable to use a hard-wire connection back from the Laptop to the Router....
_________________________

Note... A new version of MyDrive Connect has been released.....
See.... https://discussions.tomtom.com/en/discussion/1130566/a-new-version-of-mydrive-connect-released

When using the latest MyDrive Connect the menu flow has changed....
Now when using the latest version of MyDrive connect to update a NAV5 (Wi-Fi) device over USB, it APPEARS that you can update the device using the MyDrive Connect menu structure... When in fact this is NOT the case....

Clicking on the update button only opens the new MyDrive Connect "Splash screen" saying "UPDATE DEVICE THE EASY WAY" etc...

The NAV5 (Wi-Fi) devices have no access to the MyDrive Menu structures as used by the previous NAV3 & 4 devices.....
___________________________

If you choose to update a NAV5 (Wi-Fi) device over USB....
MyDrive Connect only needs to run in the background on the PC Taskbar... You can close the 'Main Mydrive Window'


That is displaying "UPDATE DEVICE THE EASY WAY" Splash screen...


Updating a NAV5 (Wi-Fi) device like your Tomtom GO 620... Even if you are updating using USB... The updating method is the same as using Wi-Fi....
ALL of the update actions are executed on the device...
Tap the 4Dot (.... Menu) --> Setting --> Updates & New Items....
If a Operating System Software update (Navcore) is required... Deselect the remaining updates, install the Navcore update 1st....

The Navcore Software Update is Mandatory you cannot deselect the update....

Then install the remaining updates....
I always install the update one at a time....
There's less chance of a log jam on the Server....

Extra Maps are Installed/Maintained... Tap the 4Dot(.... Menu) --> Setting --> Maps

Hi, thanks for the information. I have tried this, but it still won't download larger map files. Is there any way I could download these to my PC and then load them to the device? One strange thing that has occurred is that when downloading the screen shows a % complete, say 55% and then as it continues, the percentage progressively drops a few percent at a time before failing again.

I am having a problem with my Rider 550 which continues to have "update failed" which directs me to the support page, which is useless. I am unable to update the core update separately either. I have the same issues where I cannot connect to my drive connect online as its easier to update directly. My SD card is 16GB and the updates are 9GB
