Everything works but my biolite display. I know very little about the wiring, a friend with a good amt. of knowledge helped me try to reinstall in my car after being taken out for a few years. I am not sure if the biolite drivers or memory problem on the hu harddrive. Any input would be so helpful as far as troubleshooting or to narrow down what is not the problem. My alpine makes my world a good place. I can't go the expensive route, i have a good feeling with more knowledge or input from someone it will work.
