installed overhead DVD player, now the truck is "slow" to start. Help?
Ok, I had an overhead DVD player installed in my 2007 NBS silverado crew cab yesterday. Since that time, the truck has been slow to start, meaning that when I turn the ignition, there is a 2-3 second delay before the truck actually cranks. I am getting no codes, lights, or security issues. It starts with the remote start with no problem. It doesn't appear to be anything serious, other than the delayed ignition. Is this a major problem, something that I need to be concerned about?
Any help is appreciated. Thanks!

Thats strange. I've installed a lot of car audio but have never had a problem like that. Where did you tap your power wire into?

I spoke with the installer, and he says that he drew power through the dome light. I did some research and it sounds like it may have something to do with tapping into the ignition circuit? What I find interesting is that I found a DTC online, P1682, for the delayed or extended motor cranking, but I am getting no codes on the truck...

my best guess is that the overhead dvd player is drawing power even in the off position, resulting in draining the battery which is causing a delayed start. My reasoning for the remote start is its not powering up all the systems of the truck immeditaly (hvac, radio etc.) that it cranks and starts then turns everything on since the cranking is being controlled 100% by the computer. This is my best guess, I would look and see how other dvd players were installed and where they pulled power from., and if there is a way to make sure the entertainment system doesn't draw any power when not in use.

I have noticed the voltmeter running in different positions, rather than "top dead center" on the gauge.

You're heading in the right direction there with the DTC delayed crank. I suspect it's where the installer caught switched ( ignition ) power for the monitor. I have experienced this on a few GM products. Have the installer move the switched power supply wire to a different source. I usually add my own fuse holder and go to an empty spade on the distribution block to the left of the brake pedal. hope this helps.
