Brezel looks factory! How do you fabricate your Brezel?
Let me share what I have done morning in my Camry.
I installed the Carnetix P1900 and Acer One Netbook inside the glove campartment.
GPS is attached above the rear view mirror with double side tape.
When the ignition is off, netbook goes into Standby mode, and it resumes from where it left last time when you turn on the ignition. It take no time to boot up. Cartnetix DC-DC does very good job in this case. It has a standby feature that still supply couple hundrey milliam amp of 19volt into the netbook to keep it up running in stanby mode whe the ignition is off. Of course, if the shut down sequence it mess up, netbook draw more power than expected, CarNetix will cut off the power, to prevent further battery drain. My Brezel doesn't good as your. Wish I can one of your
