I bought a 2013 model s 85 to part out but have convinced myself to get it back in the road. Front end damage with air bag deployment but only 36k miles. I have replaced the pyro fuse, bypassed the radiator and bled the battery cooling system. The car now charges and drives. The only error is air suspension light and airbags. My major concern is that the car has not updated firmware for almost 2 years. The maps on the 17 inch screen are blank (maybe called tiled). The car connects to WiFi and has good 3g sign. I can stream music using the 3g data and load webpages slowly. No YouTube videos play. I went to tesla service and found out that Tesla has not blacklisted the car. Have I missed too many updates? Do I have to hack or root it? Not sure what rooting really is. I have read that the earlier firmware is easier to hack? Any advice is appreciated.
