    I am looking to install a hard wired micro USB in my car. Does anyone know of a hardwired solution that works with the Droid?

    The only reason I ask is because I have had a couple of chargers that don't work with the Droid.

    I'm NOT looking to hack apart a existing Cig Adapter. I want to get one that has the bare wires for the 12 volts already.

    Thanks,

    You are going to need a voltage regulator to drop the voltage from 12-14.4V down to 5V if you want a hard wire solution. It will be cheaper (and easier) to hard wire a hidden cigarette plug in and use a usb adapter. like this:

    Or, if you are a glutton for punishment, you could build your own circuit with this regulator:
    3A Adjustable step down switching voltage regulator

    You would need to mount it to a board, in an enclosure. Supply it with 12V, and set it to 5v out, with a female USB plug wired in on the output side of the regulator. Sounds like a lot more work than it is worth to me.

    Thanks but, I don't want to do a half baked installation. I want something that is going to last a long time and not fall apart in a few years.

    I'm looking for something like this, but for micro-USB (Droid)

    Are you looking for just a cable to connect on the Droid's end or a dock?

    I already have the Motorola Dock. I am just looking for the 12V to Micro USB adapter and cable that can be hardwired into the car. This way I will not have to tie up a (Cig) Power Outlet, since I almost always plug my Droid in while in Navigation Mode.

    Just go to radio shack and get a 12V cigarette lighter adapter. It comes with stripped ends to wire into the car and then just hide it under the dashboard and plug a regular microsub car adapter into that. It will be a neat and clean install without the hassle.

    As I stated in a previous message. I don't want to do a half-baked installation. I want something that is going to be worry-free and last a long time.

    I don't see this as being a reliable or 100% safe idea. Generally those adapters like a little air around them, not buried in a dashboard. Two, I can see the plug coming un-done and posing a electrical risk.

    I know someone has a permanent bare wire adapter for Micro-USB. It's just a question as to whether it will work with the Droid.

    check out proclipusa.com.. they have vehicle specific mounts for the droid that has a hardwired charger. its a bit pricey, but you are not gonna find a cleaner install. you just slide the phone in and it starts charging. you can get it with or without the magnet that puts the droid in car mode

    Have you actually had this work? My Garmin Cig Lighter adapter will not work with the Droid, when using a mini to micro USB adapter. The Droid is funny(bad) like that.

    The only other negative is bulking up the connector. My Droid sits real close to the gear shift lever, so I dont have much room on the left side of the droid for extra plugs.

    Thanks for the suggestion.

    No, I have 4 12V outlets, so I never need to worry about it.

    Yeah, $108 +S&H is a little on the pricey side.

    Really nice looking system! But, Like you said a bit pricey. Well over $100 for a complete system.

    The thing is I already have the mount for the Droid. I just need the power.

    I do like the fact that ProClip USA is about 30 miles north of where I live. I do like to support the local guys.

    It's a nice looking system but $$.

    I have had a "half baked" install under my console for 4 years or better. Using a female 12 volt plug from radio shake and a 12 volt male to female usb. I also use a small Huston hub to plug up different devices at that same time and have never had a problem I have poured up my phone, an ipod touch,and a tomtom.

    Hope this helps

    Thank you for the vote of confidence. It would still bother me to do it that way. I'm the type of person that solders and shrink tubes all my work. I don't use the quick-clips to tap into wires. I tie everything up nicely not with tape.

    I just don't want to have something come un-done and have to take apart the dash a second time.

    I would really like to use the ProClip system. It is a little bit costly. But, The other thing is you can remove it or hide it, when the car is parked. Just for security reasons I would rather not have any holders visible, while the car is park somewhere. My current holder is easily removed and stashed away after I park the car.

    i know i am going to get flamed for this but bestbuy did mine for like 40 dollars and you need a car charger for the droid. If you have a nice newer car like me and you dont want to get it messed up because taking apart the dash can sometimes have hidden clips then pay to have it done

    I heat shrink all splices and as stated ^ no problems. I have mine in a lowered show truck that is daily driven. So I have to have wires and mounts removable or hidden.

    And since you are so anal about wiring you are probably one of those people that does all the maintenance on your car that is recomended and for that I thank you because you keep me with a job.

    Aren't you concerned about it unplugging itself from the hidden socket? Then again, you say it's your daily driver, so it must be secure.
