My TomTom VIA 52 isn't starting up properly.
When my Tom Tom VIA 52 starts up it tells me its still connected to my computer, this has only been happening since the last 2 updates. I've looked for a disconnect from computer but can't find one. Hope someone can help. Thanks
Try a drum reset on the unit by holding the power button about 20 seconds till you hear the drum sounds.

If you're connecting your device using you cars Dashboard USB Port
See Bullet point (1)
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
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)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
(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 (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
As a test...
Try 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.....
