Most folks I've seen around town run their SmartPhones, Mobile GPS, etc windshield mounts dead center on the windshield. I spend a lot of time in my car and being left handed it was more convenient to mount the windshield dock for my droid on the left adjacent to the A-pillar. This creates a charging situation, where on long hauls GPS kills my device. I didn't want to drag the pig tail stock charger over the steering column; so I am going with a hardwired Micro USB wire. I did a quick search that came back null. I am curious if anyone else has hardwired in their phone chargers.....

 

I have 5v, 12v and 19v regulated power supplies hardwired. What are you trying to figure out? It's pretty straight forward. It's up to you to make it look professional.

 

It's not too hard to do. I actually added a USB port to my dashboard.
First you need a Panel Mount USB Socket...

Then you need something to convert the 12V in your car to the 5V that USB requires. I bought something like this and disassembled it...

Then you put the disassembled adapter in a project box. Wire up the 12V to one end and your panel mount cable to the 5V coming out. Here is the pin out for USB. Ignore the D- and D+. You only need the power part for charging...

Then find a place to hide your project box behind the dash and mount your USB socket where it's convenient for you.

 

Rebel hell - cool idea, I picked up a prefaced wire from EDO on eBay and threw it in the car today. I was interested it other sit-ups and such thanks for jumping in.
