Sorry tony i disagree

If you stick the player in and then tun the key if you are like me with a diesel you have to wait for the glow plugs to go out before you start, also i check all lights that should come on do come on before i start so i get the tuner not being detected alot but it depends entirly on how quick i start the car.

Knowing about the problem i either delay starting the car by a few seconds or just pull the player and pop it back in to reset it. No problem when you know about it in futre things it may be a problem as they will be more main stream.
