Bypassing the parking brake feature to play dvd player while driving....
 

I have a 2007 Toyota Camry LE and I replaced the stock stereo with an aftermarket DUAL flip out dvd player. I've wired everything including the grounding wire. The dvd player works fine when the car is in ACC( I wired a swith to trick it to think the parking brake is on) but the problem I am havinf is getting it to play when the engine is on. Does anybody know how to overide that problem?

The stock 6 speaker basic radio had 2 sources of power.

15A Radio No 1 Fuse (battery) and 7.5A Radio No 2 Fuse (ACC).
