Just wanted to show my car install that I've been messing with for some time now. My car install includes a USB DAC, flash drive, webcam, DVB-T for FM stations and a Joycon for steering wheel controls. All of these are connected to 2 USB Hubs that are externally powered.

I have the webcam mounted for my backup cam but am having some problems with it in the daylight so I might ditch it if I can't figure out a solution.

As far as reliability I drove 9 hours back to college with no freezes or hiccups. Since I made my hub externally powered the tablet get enough power to stay fully charged over long trips while using gps and screen brightness on full, but I should not have any problems with it staying charged with Timurs new USBROM that can enable fast charging.

I also have a few hidden buttons in my center console for the 3 tablet buttons and also a charge button to charge the tablet even when the car is off if the battery get low, for example its been below zero for the past week so my battery is probably extremely due to the extreme temperatures. I normally only lose 1-2% over night but since I haven't been driving my car these past couple of days I have lost ~20% in a 24hr period from the -10 degree temperatures we have had, which is when im glad i added a charge button so it can charge while i'm in the store or class or something.

Oh and for GPS and wifi antenna I ended up mounting above the headliner on the passenger side and ran wires to the connectors.

I'm currently using
-Timurs USBROM with kernel built in Link
-Power Amp
-mediaU to stream local radio stations
-Copilot
-Apex Launcher
-GMD Gesture Control
-Tasker
-Tablet Talk
-SDR Touch
-Probably others that I am forgetting

Videos at the bottom of this post.

If you have any questions feel free to ask!!!
What do you guys think?

-$39.00 Joycon EX Steering Wheel Control PC Interface

-$55.00 FiiO E10 USB DAC Headphone Amplifier

-$180.00 A new Amp and Speakers to replace my factory bose

-$37.00 64GB Flash Drive for all my music

-$10.00 OTG Y Charge Cable

-$24.00 Digital to Analog Audio Converter

-$10.00 2 DC USB chargers for the HUBs

-$72.00 Trailblazer head unit wiring harness to keep onstar and door chimes

-$34.00 Mini Bluetooth keyboard

-$33.00 DVB-T Tuner

-$10.00 DVB-T Antenna

-$7.50 Another USB HUB

-$15.00 4 USB extensions to make USB HUB externally powered

-$21.00 3 10FT USB extensions

-$13.00 Wire to extend GPS and WIFI antennas

-$5.00 DC 2.1A USB charger

Total = $610

Of course you can do this for much cheaper, since a nice chunk of that went into audio equipment and extra accessories.



4 channel amp


Bracket I made to mount the tablet to. I added a fan to help keep the tablet cool along with some velcro to mount the tablet to my bracket.




Had to add some wires for the power, volume up and down buttons that I ran to the center console in case the tablet freezes or something. Also had to run wires to the back cover since the wifi and gps are basically stickers on the back cover which I just velcroed to the top of the stereo opening.




Mounted


RCA digital to analog converter


USB hub with my flash drive, steering wheel controls, backup cam (still working on) and also my usb DAC which is also in the pic


Poweramp

Installed

All of this is mounted in my Trailblazer

Already have a PLX kiwi OBD adapter connected to my old original droid one that is permanently mounted on the top of my windshield. Rather have torque up 24/7 instead of flipping through screens on the tablet.
Thanks for the suggestion tho
Now I have a pillar pod don't really even need the torque app either, but I'll prolly just put different gauges on the phone

Had issues with the amp so ended up splitting my rca cables and having 4 inputs and had to set the amp to 4 channel.
Then ran new wires to each door.

The amp have pre-amp out plugs that I then ran to 2 separate amps for each of my subs.

Still need to fine tune all my amps but it sounds much better than before!

Well went and cleaned a foot or two of snow off my truck today and apparently the tablet battery doesn't like temperatures below zero, well at least for a long period of time. My tablet battery was dead along with my trucks battery.
When I tried charging the tablet it showed it was charging with it off but once I turned it on it immediately shut down and said battery zero. So I let my car warm up for about 40 minutes then let it just sit for another 40 minutes and then tried charging it. It then finally took the charge and turned on.
For the past 3 days I haven't touched my car since its been below zero every day. I believe the coldest it got was -14 with a wind chill of -44 so I'm not surprised my tablet was dead, I was just surprised that it wouldn't take a charge. Not really sure what happened but I think the battery froze which is why it wouldn't take a charge. I think this because if you look at the graph it had about a 40% charge left before it just dropped right off to 0. Here is a screen shot I took of the battery graph once I got it turned on and charging for 2 hours.
Tomorrow has a high of 7 so hopefully it will stay decently charged.

Battery Problems
You could warm up the car and get the battery charged up normal. Then remove the battery and test the voltage output. Then just get a dc to dc converter that applies that exact voltage and connect the power supply to ignition. Then the output of the power supply into the connector on the tablet that used to connect to the battery. This would eliminate your battery problems, unless of coarse your vehicle battery was dead but in that case you probably aren't going anywhere anyway!!

Sweet install!

I'll be doing the same thing as soon as I get my tools back in a few months - I'm in the middle relocate so my tools are in storage... somewhere.

I'm wondering about the backup camera. I've seen a thread or two about getting a webcam to work but it appeared that the app had to be launched manually. Did you find a way to get the app to start automatically when the reverse lights come on?
