How I can update a map when TomTom tells there is no internet connect?

Hi
@kari.heimone
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"

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... (1) MyDrive Connect will only show a "Splash screen" saying "Connect your device using Wi-Fi" etc....


If required you can close the 'Main Mydrive Window' showing the "Connect your device using Wi-Fi" Splash screen... MyDrive Connect only needs to run in the background on the PC Taskbar... The NAV(5 Wi-Fi) devices have no access the MyDrive Menu structures as used by the previous NAV3 & 4 devices
Updating a NAV5 (Wi-Fi) device using USB is the same as using Wi-Fi, all the update actions are executed on the device...
Tap the 4Dot (.... Menu) --> Setting --> Updates & New Items
Extra Maps are Installed/Maintained... Tap the 4Dot(.... Menu) --> Setting --> Maps

Stay Safe... ATB YFM
