How to bypass a park switch for a jensen model VM9212N

cant control the volume knob try to turn down blasts the volume instead

This only works for Model: VM9511TS Brand: JENSEN I have only tried it on this model because this is the only one I have from them. It might work on other Jensen models. Try it and if it succeeds please repost letting us know what model number it worked on, so that others may enjoy watching TV while driving!!!! ;0)
To BYPASS the parking brake function you have to first have the remote control that came with the ts head unit. 
If you have already set up the parking brake function as suggested in the owners manuel follow these directions below!
1: Press the "STOP" button on the remote twice 2: Type "1.2.6.4." on the remote. 3: Press the "left(reverse) arrow" button as if you were going back track on a cd. This must be done very quickly in sequential order. It took me a few times to get it, but it was still tough. Don't give up though keep trying and you will get it.
Once you have the screen up to manually override the "E-Brake Safety Control", you must then change the settings for Region and Macrovision.
My settings are as follows and I live in the Chicagoland Area;
Region: 1 E-Brake Overide: ON Macrovision: OFF
Macrovision: Having this feature off allows you to play burnt DVDs and other burnt discs or non-copyright protected material!

Hope this helps anyone out there. However, I must not take credit for this code because I found it online and purchased it from an ebay power seller. 
Take care,

Hey guys,
i have a Jensen VM9212N and i am not able to set up that Anti-Theft password. Also i read on internet that we can update the wallpaper on the radio.
Does any one knows how to do that?
Thanks

with by passing the screen so u can watch dvd's while drive is simple... look for the pink wire in ur head unit and when u find it, it will lead u to the hand brake but wat u do is disconect the wire from the hand brake and earth it out like wat u do to ur amp and it will alow u to watch it any time...
