Tesla head unit gen 2- it's already rooted and has latest firmware update. Works fine and includes hook ups. Selling because I own a Jeep now and the dealer didn’t give any extra for it. Works perfectly. Asking $400
So I installed one screen was working messed around on it turned the car off went inside and came back 15 mins later to mess with it some more and now it won’t turn on. Any ideas on what I did wrong?
