so the Chief will have to accept the fact that he has to power off his scanner manually to save his changes.
What puzzles me is that there's another chief's car with an SDS200 wired the
same way and that scanner doesn't have this problem.
Still does not explain why one 200 does this and the other 200 does not. Are they both wired the same way? Mine came with both a 3 wire harness and a cigarette lighter plug.
