Go professional 520 keeps crashing

Scotty1

Can anyone help my 520 truck sat nav keeps crashing I've put it in recovery mode several times I've I've factory reset several times but still crashes I've had it about 3 years so thought I'd get a new one and brought a brand new 520 truck and the exact same thing is happening to that anyone got any thoughts? Surely it cant be the device as it's even happening on a brand new one!!

HI
@Scotty1
Welcome to the site....
The Previous NAV4 and Latest (NAV5 WiFi) devices are quite power hungry and can go into "Power saving mode" if not supplied with enough power
Are you using the Tomtom supplied cable and Tomtom supplied Power Adapter
The Charger Adaptor and USB Cable supplied by Tomtom WILL run and charge the device at the same time

Many 3rd party Mismatched Charger Adaptors won't run and charge the device at the same time
See... It's not simply a power thing.....

_____________________________________

When the device is In use they are designed to be always connected to a power supply
The Tomtom supplied Power Adapter is rated at 5Volts 1.2Amps
Even after you have recharged the device externally via a mains charger, when in use in the vehicle, they will still require being connected to a Tomtom supplied Power Adapter (Or a proven suitable 3rd party Power adapter)

(1)... Do NOT attach them to a dashboard USB port in your vehicle as they normally only supply 500mAmp (0.5Amp) and are for data transfer and not supplying power: See... Note (1) & (2)

(2)... Using a NONE Tomtom 3rd party underpowered or a mismatched cigarette lighter charger can cause the device to go into Power Saving Mode: See... Note (1)

(3)... On the Models with a built-in SIM, the reduction of power to the SIM can cause the dropping of the traffic info: Note (3)

Note (1)... At an (Undisclosed) percentage of battery discharge, the device will try to save its power requirements by dimming the screen and eventually powers off the device... Devices with a built-in SIM Card may also lose Live Traffic services
Note (2)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
Note (3)... I tried connecting my Tomtom GO 6200 to my Cars USB port, checked the connection status it reports 'Connected over USB' --> 'GPRS (SIM) Disconnected'

Thanks for your comments but I've only ever used the tomtom charger and cable it came with the first sat nav has been fine for 3 years but only over the past month or so has been crashing as for the brand new one it done it on the first use!
