I don't know if this is old news or not but i just stumbled across this so it might be helpful for others.

I'm assuming this will work with all other car dvd players that are wired to where you must be in park and have the hand brake applied twice before video will appear.

OK, this is what it can do-

The purpose of the safety feature is to not show video while in drive.... however, a glitch in my Alpine allows to show video while i'm driving and only shuts it off when the brake is pressed so for road trips, , you need not a video bypass.

What i did-

While i was in a stopped position, you could even consider just starting the car a stopped position because you only need to do this once unless you shut the car off.

While in a stopped position, have car in Park with the hand brake OFF. Stick in a movie. The movie's audio will play but no video. Raise hand brake. If still no video, without reapplying the physical brake(because u are still in park), release the hand brake and reapply it.

Now you should have video! This is normal so far.

Now, this is what i did next-

I took the car out of park while the hand brake was still applied( make sure you are not on an incline when doing that).

You should still have video. If you do... then that's it!

You can now drive WITHOUT the hand brake applied AND allowed to be in Drive with full video. The only time the video will shut off is when the physical brake is applied and held down. If you are stopped for a while and want to see what is going on, while holding the physical break(since you are currently stopped), apply the hand brake then let go of the physical break completely. To move out of your current stopped position, just release the hand brake and drive.

Since the video only shuts off now when the brake pedal is applied, it makes it a lot more convenient.

This is intended for those who either paid to have the stereo installed or those who installed it the right way and don't feel like payin the $17-$30 for the bypass PLUS either takin your car apart again to install it or finding a "shady" installer to do it without proof.

So, hope it works out for you as easily as it does for me. also, while there is no video, there is always audio playing so you are still "involved" with the movie for those few brief seconds where you might not have video when the brake pedal is applied.

Now you see how effective this technique is for road trips.

This is a lot of work..

My PAC bypass was a BREEZE to install and I don't have to do anything to start playing movies.

yes but i had mine installed, i dont feel like reguttin the inside in 30 degree weather.

This procedure to engage the "glitch" only takes 8 seconds. After that, i drive away.

I just wanted to break it down in very simple terms so no one is lost, hehe.

Sounds simple enough. I'm glad mine was easy, I just grounded the parking break.

hope it works. I just use the good ole bypass for my head units.
