I have a 2012 Hyundai Tucson Limited and I'm having issues where I'm not able to click the "accept" button for the navigation system when I start my vehicle as it's grayed out. I'm able to use other functions of the system such as the back up camera and radio, except my navigation system. I tried using the reset button, pulling the fuse, unplugged the battery and nothing has worked so far. The car is currently out of warranty and Hyundai wants $1400 to replace the system. Does anyone have any other recommendations to try?
