Batboard

Stupid question.

I have a Panasonic PDRC 12.1 in my work car and the damned screen shuts off 99% of the time when the car starts up. I have tried running a meter on the battery and on the power cable itself and get a variety of readings on startup, nothing consistent enough to say that voltage is dropping significantly, in fact it appears to spike at the end of the cable. Since the power supply for the display was hooked to the "accessory" cigarette style plug, we tried moving it closer to the battery (connecting it directly to the battery, even), and although we initially had the screen shut off fewer times, it eventually came back. In any event, this is getting to be extremely irritating.

Anybody have any ideas?

Still searching...it seems like a small, 12v UPS will do it. Anybody know where I can find one? Lind makes one that attaches to a lead acid gel battery, but a fully integrated unit would be way easier.
