    This is my 'old' GO 400 which I seem unable to update.

    I plug into a USB port on the PC, and after booting it up the device says 'No Maps Available'. I log onto MyDrive Connect and it shows 840 Mb used 6214 Mb free. It also shows my previously inserted and formatted Samsung 32 Gb SDHC (Class 10) memory card as 30148 Mb free.

    I click on the map of Europe that I want to install, and for the next 6 hours or more I wait patiently whilst it says it's downloading it. It then goes into the next phase which is 'Updating content on your device'. After some time, at or around the 20 per cent mark, it stops. At this point I notice the GO 400 screen is completely black. No matter how long I leave it, nothing further happens. I presume the device has actually shut down as I have to press the ON button to boot it up again.

    Computer has no power management or power saving enabled for the hard drive, Ethernet adaptor or USB hub/ports. I have not lost power at any point, and the Internet connection is constant and not being used by anthying or anyone else. I even tried a different USB lead and another Windows 7 computer. I am plugging directly into one of the backplane USB ports which is inbuilt onto the mobo.

    I've been through this exact scenario about five times now, and each time it fails precisely as above.

    Anyone got any suggestions please...

    Try just disconnecting and then reconnecting the USB cable again.
    Has helped in the past with various models, even a GO 600.

    Pretty sure I tried that once, but will give it another go and report back later.

    Incidentally, whilst the GO 400 is in this state (i.e. No Maps Available), I am unable to determine the state of charge of the internal battery. That is, unless I manage get it into 'linux' mode. But that's probably not the correct screen...

    Ok, well it completely failed to turn on just now. Looking at the 'linux' screen, it tells me Battery Charge Level is 1% and counting down (2775 mV), then screen goes blank. Does it not charge when in this mode?

    I wonder if that's why the updates keep failing...

    Sounds as if the battery is dead.

    Yes, that's the way I'm leaning towards now. Either that, or the charging circuitry. I kinda thought that even if the battery was not able to hold a charge, the fact it was plugged into a power source, i.e. USB socket, it would keep working. Rather like a laptop computer - if the battery is flat/kn*ackered, the mains charger will keep it running. In fact, most laptops will run on the mains adaptor with the battery completely removed. Is that not the case with the GO 400?

    Hard to test as there is no removable battery.

    If you don't have a mains USB transformer use your cellphone USB charger and see if you can power up.

    Been there, done that!

    Currently have the device in pieces on the bench, and battery shows 3.72v on a DVM. Since this Maxell Li-ion battery is marked as 3.7v 720 mAh, I'm guessing it's actually fully charged! There's nothing visibly burnt or blown, so I'd say some of the circuitry on the pcb is faulty, and guess the whole caboodle is probably toast now...
