clock stopped working on kia optima 2017

Navigation clock stopped working. I updated the system. It.took 20 minutes, but it started working again. Hope this helps.

I tried updating system and was told to unplug USB stick I use for music. Did unplug, but the system still would not update. Bummer.

This just happened to me too yesterday. Very strange.

It just happened to mine as well, 2015 KIA Optima SXL

I called Kia go into setup and click update this will take a while , they stated you may have to do this a few times , I only had to do it once and it came back on keep car running .

When I go to update, it pops up saying please check the update memory and try again. Where can I find that?

This is what mine is doing trying to update the system

Mine too! Does anyone know what to do when this pops up? I've checked the memory then go back to this and it gives me the same response.

This works

Disconnected battery for half an hour. Worked for 2015 Optima SX Turbo.

Thabk you, I'll give it a try.

2017 Kia Optima, same problem with clock. Disconnected the negative on the battery for 3 mins. It now works:)

Disconnecting the negative cable and reconnect ing after 5 minutes worked for me! Clock started right away!

Optima SX 2016. Same thing, disconnected negative for 5 mins, success!!
