When we bought a used Kia Optima PHEV (off lease) it was missing the Maps SD card that plugs into the infotainment unit, so the onboard maps & navigation did not work. Given that every phone now comes with multiple GPS navigation & mapping options, this wasn’t a deal-breaker, but I was worried that this would be a very expensive dealer only purchase if we ever wanted to get it working.
I was very pleasantly surprised to find out that Kia will sell and ship you an SD card with updated map data and infotainment software for only $25!

I was even happier to find out that if I didn’t want to pay the $25 and wait for shipping, I could buy my own 32 GB Class 10 SDHC UHS-1 card (For $10), download their (Windows or Mac only) software and use it to write the data out to the card myself at home!
