Tablet install, need 5V source - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

spadz93 · 01-04-2016, 11:44 PM

Got an old samsung tablet kicking around, so I'm going to mount it up and use it to run Torque, maybe Google maps for navi, and some media playback.

Mounting it isn't an issue, but rather trying to find a power source to keep it charged is my concern. Ideally, I'd like to have it only charge on ignition. Would the best approach be to step 12v down to 5v (most likely from the factory cigarette lighter since it's ignition/switched), fuse it for 2A and splice a charging cable in, or is there a 5V source that's hanging out around there already? Got a few wiring diagrams and the only 5V source i'm seeing is at the BCM, but I don't want to tap that if that's going to make thing's screwy.

Wouldn't a USB charger work?

It would, but i'm going for a more tucked-in look rather than having a wire hang from the tablet and just plug into the cigarette lighter

Post pics when you're done!! I have a Nexus 7 that isn't being used and just recently tried to think about how/where to do this exact same thing. After 20 minutes just sitting in my driveway and messing around with the "where" of things, I had a semi-decent idea of what I wanted to do, but can't for the life of me think of a clean way to do it.

Not sure where you're looking to mount, but I'm looking to do it just to the right of the dash, I think.

Maybe wire up a third hidden power port and use a USB cigarette lighter adapter.

I bought one of these for my front camera DVR recorder. works flawless.

Found an old iPhone car charger with a busted port, and cut the chip out to use as a stepdown. Wired it to the cigarette lighter, but that runs off of RAP, which doesn't play nice with my remote start system (long story short, if i "prime" my remote start system, the tablet doesn't shut down like it should), so I have to find an ignition 12V wire in the harness for my 4pack gauges (anyone got a wire color? I'm assuming red or pink).

Got it up and running as well as mounted. Used a small piece of plexiglass with 3M double-sided adhesive to get a nice, smooth surface, then used a suction cup mount on top of that since I couldn't find an adhesive mount. There's a video on my IG of it running real quick, hopefully this link works https://www.instagram.com/p/BALCFbnGKvl/

Maybe this might help...

spadz93 · 01-06-2016, 01:57 PM

Mounting is all taken care of, I just need that power wire. Pulled this picture from an install sheet from gen5diy, wondering if it's a switched 12v wire

While I'm figuring this all out, anyone got any other cool app recommendations? I feel like I'm only scratching the surface with torque and Google maps. What other cool car apps are out there, if any?

I would also like to know which wires on the radio plug harness is positive and negative when the car is turned to ACC or to ON!!

Why don't you just tap the 12v outlet, add a hidden outlet and throw a usb plug in there, and plug it in behind the dash? Instead of searching for a stepping down a different 12v source?

spadz93 · 01-07-2016, 05:33 AM

Okay so here's the deal. That 12v outlet is controlled by our cars Retained Accessory Power circuit. This won't work with an aftermarket remote start system (which I have) for the reason that it'll leave the tablet running for 10 minutes after I get out of the car. Bear with me on this one:

With a remote start system on a manual car, you need to prime the system so that it knows that when you remote start the car, it won't start in gear and fly down the road. To do this, you need to engage the foot brake, then the parking brake, and then click the start button on the remote to prime the system. After clicking the button, you remove your key from the ignition, but the car remains running. You then need to open your driver door, get out, close the door, and then lock the car (normal process). It's not until AFTER you close the door that the car shuts down. This is normal function for a remote start system on a manual car, as it's the only way for the system to verify that the car won't remote start in gear. However, this process leaves the retained accessory power running, since you can't open the door to kill the RAP (the remote start system will "unprime"). I already had to build a relay harness for my radio to kill the radio for when I use the remote start, which I may end up tapping if I find no luck elsewhere.

The main goal is to have the tablet act as part of the car: I turn the car on, it wakes up and links to my obd. I turn the car off, tablet goes to sleep because it's configured to sleep when the charger becomes unplugged.

I hope this makes sense in explaining my goal lol, it's a complicated setup, but it can be accomplished to work simply, just need that one wire

No, that makes perfect sense, you explained it very well! I'm actually doing something similar (the obd idea, not your whole setup) with a tablet currently, but moving to an integrated carputer soon

bigwayne3000 · 01-07-2016, 06:38 AM

So you or people with remote starts on manuals are already in your vehicle when starting it? Why the **** bother having remote start then?
