[QUOTE="HardofWhoring, post: 8829318, member: 674149"] That doesn't make any sense. The directions say to hook it up to the parking brake. The parking brake is engaged when the car is off. You start the car, and then disengage the parking brake. --- For a delayed relay to be required, then you would be required to take off the parking brake before every time you start the vehicle. Then once started, you would need to reengage the parking brake to setup the nav on your stereo (every time you use it), then take the parking brake off again to drive. For a delayed relay to be needed, your normal operation would need to be: Get in car, take PB off, Start car PB on, to Set nav PB off to drive. Its not. You Start, Set nav, pb off, then drive. (and that's by what the manufacturer says). That wire is either ground or hot. You can connect the head unit, then add an extension piece to that wire and touch your battery terminals to find out. Start with batt neg. Once you find out, you wire it in permanently. I THINK its that when your PB is engaged it is ungrounded. [/QUOTE]
