Go5000 doesn't get enough power from car installation

I have a tomtom active holder for my GO5000 in my car, it's a fixed installation so it's directly tied to the cable net in the car, through a TOMTOM car charger.
This is an older charger, probably from my previous tomtom device, and it doesn't give enough power to the device, as it often goes into emergency shutdown as soon as the power is off in the car.
We've gotten the battery in the tomtom go5000 replaced, as I thought it was just worn out, but that hasn't helped.
I've looked at the tomtom page, and I don't see a 'fixed' car installation kit for Go devices, so what are the power requirements for it? I can easyli install a 5V 3A charger, I have them almost on stock for other things, would that be enough for it?

    Welcome to the site....
    The Previous NAV4 and Latest (NAV5 Wi-Fi) devices are quite power hungry and can go into "Power saving mode" if not supplied with enough power
    The Charger Adapter and USB Cable supplied by Tomtom WILL run and charge the device at the same time

    Many 3rd parties Mismatched Charger Adapters 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'

    Stay Safe... ATB YFM

    Hi @YamFazMan
    Thankyou for the swift reply, I would very much like to have a tomtom fixed installation, but I can't find a kit for it, that's why I am looking elsewhere, can you give me a link for one? I really don't want it connected to my car lighter plug, as that is in the middle of the car, and the tomtom is mounted on the A-post in the left side of the car.

    So please, if you can, point me to a tomtom fixed installation kit.

    If it helps, I got Halfords to install a fixed installation which cost about £30 including the actual kit required, they do have kits for SatNavs and Dash Cams if you want to do it for yourself.

    Hi @CJO
    Well, my problem is that the one i have is an original tomtom, but just an older version, so it probably only delivers 'just enough'.
    I don't have a problem with replacing that with a new kit myself, but it would be nice if I could get a kit that I would know would work.
    It's all good and fair that it fails for many reasons, I am more interested in a solution that doesn't fail. Previously Tomtom had kit's easily available, but they seem to have given up on that.

    Well, not really, the suggestion by YamYazFan is too dangerous, and the other is not realistic in Denmark, I could probably get a car electrician to hook it up, but it will cost around DKr 1500 (around $200).
    So I've ordered a USB charging kit for a fixed installation, that will output 2A, I hope that will suffice.
