i have the Pioneer AVH-P7500DVD, looked through the manual and saw
that it can only be viewed while the parking brake is on. But I'm
putting it in a "limo" so I need it to be able to be on all the time.
I think if i just ground the "parking break input" to the chassis,
that will fix that problem. But I'm just making sure, if anyone has
any input, please let me know thanks.
