In-car Electronics

Infotainment system (audio, GPS, phone), rear entertainment system, backup or other camera/sensors, head-up display.

""The parking sensors switch on when standing still (like at a traffic light). In other words, they seem to be too sensitive, and can't be adjusted.""

Display screen goes blank

""The navigation media screen blanked out along with associated controls. I was able to connect my cell phone to hear radio, but no other audio, GPS, etc., available on this screen. The dealer believes something may have gone wrong during an over-the-air system update but was not able to repair it. The dealer installed an all-new screen and system under warranty four years after car purchase. I had to re-program all the radio presents. I lost all my previous saved GPS location settings. I had to contact Sirius XM by phone because the electronics had a new serial number. I gave SiriusXM the new serial number and re-connected. But I was happy with Hyundai and my dealer as they stood behind their system and absorbed all costs.""
