i have a 99 ml 430 and i recently installed an in-dash navigation system/tv. i hooked a toggle switch up so it would play while driving but now the parking brake light is on and its making the terrible beeping noise. my question is....how do i either bypass the alarm or disconnect it alltogether????? i have asked all the local service people and they wont help bc its a "safety feature". i know this and i just want to bypass it. anyone have any ideas?
