Clock

[Richard Wood]

A couple of times my chr 2020, the time on the clock change’s back to winter daylight saving time. Anyone else have this problem

If Battery was not disconnected I would first suspect it droping out ie resetting on low Battery voltage.

This is the first thing I would look at but you need a volt meter to check this set on 20 volts DC and check voltage when it accurs without starting car.

Noticed too that my sat nav arrival time sometimes shows an hour ahead of the actual time I arrive and then sometimes the arrival time is  correct.  The car's clock is always correct with GMT though.  Weird !!

I've not got a solution, but want to make sure I understand what you mean.

- Daylight Savings setting goes from On to Off in the Clock settings screen?

- Is it set to update automatically (Auto adjust by GPS)?

The button says on, but  it still changes from summer time to winter. So I turn it on and off a few times, then leave it on summer time. A couple of weeks later  it changed to winter, button still on.

and it’s set for auto adjust by GPS

I have to change mine nanually by selecting daylight saving time on or off.

Its not automatic.

That sounds like a software bug. Have you tried doing a reset? Disconnecting Battery. 

After that, I'd raise it with Toyota. Maybe there's an update?
