    Above Tomtom slots into unit in Toyota Yaris Spirit, but can't get GPS signal, and will sometimes turn off.
    Have changed battery in above Tomtom. Worked in the car for the first time last week. Struggled to pick up GPS signal, but did eventually, then turn itself off. Works remotely fine.

    Could it be the unit in the car that is faulty? Was thinking of changing the whole unit?

    Grateful for any help. Able to connect to computer and update. Have a 2gb Sandisk SD Crd in it aswell. Not sure exactly is this correct.

    Thanks for any help or answers. Much appreciated.

    The first time after a long siesta in a desk, it can take as much as 10 minutes for one of these to pick up the almanac data from a satellite that allows it to know where they all are, and get a proper fix.
    The 'turned itself off' is another thing altogether.

    One wonders if there is external power to the device when it's installed in your Spirit. If not being charged while in use, it will shut off eventually. Don't have a 410 to play with, but please check
    the lower left corner of the map screen - well, almost the corner, above the blue bar. With no external power, you will see a tiny battery there, colored green if full, red if nearly empty. With external power, that battery should disappear. With the vehicle running, therefore, you do NOT want to see the battery there.

    Yes, a 2GB card is what that device can handle, and the card must be installed for the device to operate since it has no internal memory of its own.
