Hey I have a problem. THis mod works great for me except in two conditions. 1 if i turn on my car, then have it on for like 5 minutes, turn it off, turn it on again and nothing from the screen. Also, when i park my car for the week in the schools garage, i go out to it the following friday, and the screen wont self power. It seems to work fine other than that, like overnight stays, if i go into a store, etc... just not short or long intervals.
