Radio delete and in-dash tablet install for NAV & OBDII

I did this in my Jeep XJ, and now I've doing it in my bus. I deleted the in-dash radio and replaced it with a Google Nexus tablet computer. This functions as a real-time engine monitor, as well as moving-map GPS navigation. I can also link this tablet to my iPhone for internet access, so I could theoretically surf the web... or watch movies, youtube vids or porn while driving down the road. Of course I never do this. Might get arrested, go blind...or worse.

For music I installed an amplifier, connected speakers, and connected a $30 USB-powered bluetooth adapter to the amp's input. This allows me to link up my phone and stream Pandora One ($5/mo, no commercials), play content stored on my phone...or link up the tablet and play content stored on that. I no longer have a radio or CD player...but I no longer have a need to carry CD's and there's nothing but stupid sh!t on the radio anymore.

I connected a bluetooth OBDII adapter to the port under the dash; it links to the tablet and allows use as a real-time engine monitor using Torque Pro (available at the Google app store for $5) Powerstroke diesels have a shitload of engine sensors and Torque Pro has a predefined set of PID's for Ford which will read them. You can add, delete, configure all kinds of different instruments all kinds of different ways. Graph trends, data log, add inputs...I've just scratched the surface with this app.

For navigation I use Backcountry Navigator (paid version), which allows map downloads at varying zoom levels for offline use (when you have no connection). To download I will pull up behind the house and pull wifi signal from the house router. All kinds of possibilities w/ this app; again I've just scratched the surface.

For city navigation I can link the tablet to my iphone and use Google Maps...or just use my iPhone itself.

Google Nexus 7 has a really good internal GPS antenna; much better than most tablets according to my research. The 2nd gen Nexus 7 can be had used on Ebay for damn cheap; I paid $60 for a used 32GB wifi model.



OBDII adapters have come WAY down in price; this one here is reputed to be good and is 9 bucks on Ebay. 9 bucks. Amazing.



For a mount I cut out a piece of plywood (4" x 7.5"), countersunk a couple 5/16 bolts, which go thru the plywood and thread into a piece of 2"x .250" aluminum stock that's about half an inch longer on each end. The longer ends grab the dash inside the hole and clamp the plywood firmly to it. Then some industrial strength velcro from Lowes. 3" x 4" works nice on both sides. In this pic I have yet to velcro the plywood. You can see it on the tablet laying face down below it.



Here it is on the dash:




Nav screen:


Instruments I'm using:
Engine coolant, Engine Oil Temp, Trans Oil Temp, Fuel Inj Control Module Voltage
Boost, Batt voltage, High Pressure Oil Pump pressure, Injection Pressure Regulator duty cycle



Charging: Requires a 90 degree Micro-USB cord that will tuck in behind the tablet, plugged into a 12v USB charger wired in back inside the dash (or wherever) You want a 3A charger...or the tablet will go dead w/ extended use of several hours. Like these or similar.

For me, this gives me everything I could want. I'm sure there are many more possibilities. Like I said, I've just scratched the surface.

They do have some, and the good ones have LOTS. But they're not ALL good.

The 7.3L in my 99 F350 is a hairy-chested brute of an engine, electronically controlled and (with a few mods) reliable as it gets. The next-gen 6.0L in this 04 short bus is WAY more complex, with alot more to go wrong...and go wrong it does. apparently subsequent engines to the 6.0L (6.4 & 6.7) are even more and even worse.

All of this driven by those weasels at the EPA.
Then again...go any number of places that lack these weasels and the smog will choke you.

That is a great idea, it's too bad the full size buses do not use OBDII. But for the music, that would work on anything, very cool.

I did this in my smart-car.. although I used a device that actually has AM-FM in it... then used a Miro-cast device so I have features of Androiud-Auto / Apple CarPlay in it..

its a really cool thing to do as long as you keep your tab cool.. much better than the crappy or no-radio.. and you can take the output of your tab and run it into an AMP and still have good audio controls, as well as fade / balance, etc..


the unit I used in my smart car has a few side-buttons on it that i tied to apps.. so I can press a hard button and go to my Navi App, or music, my OBD-II, etc..

rockin! i love this.

I like the setup and I like all of the thought and expertise behind the setup. My only question is how do you charge the tablet? Do you take it off every time you need to charge it?

Interested in this as a radio ADD, not a delete...
But, very droid ignorant. JBiPhone 6S+ only here, except for those damned Amazon Fire xd tablets I bought the kids a couple Christmases ago... Ran them long enough to hate them during setup!
Which tablet is a good place to start? I searched CL heaven and found prices all over the place!

And don't be intimidated by the android functionality. Its different from iPhone but its just to get an android tablet and muck around with it until you recognize the patterns. And if you get stuck, get on your computer and ask google "How do I (insert question here) with android?" Then look thru the results until you find what you're after.

for those that prefer iOS you can do this with an iPAD as well... Wi-Fi OBD-II modules will work with it and the Dash-Command software.. while its not as customizable as Torque it is nice nevertheless..

GPS-wise the iPADS with cellular capabilities have built in GPS chipsets.. the GPS will work even if you do not activate the cellular account on the ipad.. you can find first or 2nd gen ipad minis reasonably priced now...

I run Co-pilot Truck on mine which is an off-line GPS, all the maps are downloaded..

since my DEV bus is purely mechanical I have no beed for OBD in that bus... my new T-444E doesnt use OBD-II it has the IHC PCM so I doubt i'll find a scanner to read it.. havent looked into it yet

the OBD-II portion is useful for those that have Cutaways like the E series and GMC short busses...
