2013 Yaris Hybrid SatNav map problem

[dwilden]

Hi,

My 2013 Yaris Hybrid has a Toyota Touch and Go Satnav system. In the cold weather, the map never finishes loading when the car is started - it just displays a spinning disk symbol, even if the car is driven for an hour or more. However if I turn off the ignition and turn it back on, the map loads after a few seconds. This is fully repeatable, ie same happens every morning from cold.

The car is still in warranty, but the dealer is treating it as a software problem. They told me that they would reinstall the map software, but after having the car for a full day, I discovered that all they had done was reset the radio, which did not fix the fault. I think they are now intending to reload the map software, which means leaving the car with them again for a day.

As the problem is temperature dependent, I suspect the fault is hardware related - possibly a memory chip fault - and no amount of software reloads is going to fix it.

Has anyone else come across this problem, please?

Regards

Dave
