There are ways to get around that bypass. You can buy a swith box that will do the bypass for you. The reason the screen doesn't work while the parking brake is down is because the screen and the A/V receiver are wired directly to the power wire of the parking brake. You can get around this by grounding the 2 wire leads that are to go to the P Brake. This cannot be done by a shop. By law they have to wire it up correctly. You would then have to go rewire them yourself. Then again, by state laws that is illegal.
Precisely what I did . . . . after I got the car back. It is distracting to have it going while driving. . . which is why I simply don't do that. However, having the ability to do that while a passenger watches is pretty cool. . . and unless it's at night it's really not THAT distracting. During the day you have to really look at the screen to get your attention. At night, it's hard NOT to look at it.
The laws that govern this activity are loosely related to the mobile phone laws that are springing up everwhere that states it's illegal to talk while driving. . . which brings up the arguement that simply having a front seat passenger can be distracting. . . . especially if they're "interacting" with the driver in certain ways. :wink:
At any rate, common sense should rule, here.
1. At all costs, do your best not to play video while driving
2. Use a handsfree or speakerphone feature for mobile phones
3. Try not to get road h**d while on the road (which defeats the purpose)
