Installing a Nexus 7 Tablet in my dash.. this will replace the radio

I have a tuner that will interface with it for AM/FM/HD

I have an USB DAC for audio interface.. It will also have a USB thumb drive that will store music as well. The thumb drive will be accessible and if I connect my phone it will get the Data connection for use with the maps etc..

Yeah last year, I liked it but There were some things I did not like..

I had it set-up to access my phone, the issue I had was the connection was sometimes buggy, While I know it was not an official app for the radio, I accepted it. Then when I got a new phone I need to find a new way for getting the android content on the radio, I was going to do a Android PC but had some driver issues and such, then finding a way to keep it in a sleep mode etc.

Sure..

Here is a list of components
Nexus 7 (2012) 32gb
Directed DMHD1000 AM/FM/HD tuner
MJS USB interface cable for tuner
USB OTG cable
USB HUB
Behringer UCA-202 (USB DAC for Audio)
USB Thumb Drive for music content

Android Apps/ROM
-Timur's USB ROM which allows for fixed install, deep sleep and USB Host control while charging.
-Tuner control I am using b0b's HD tuner app
-ALDLDroid for direct connection to my ALDL whenever needed
-Pandora
-Slacker
-Nova Launcher
-Might use Car home Ultra which I really like, but the formatting is not quite right on the Nexus)
-Rotation locker to lock rotation to landscape (Slacker main menu needs this)
-Google Drive

For a mount I disassembled a 360 tablet case, the piece that tablet snaps into is plastic and fits nice in the dash.

I had to modify the bottom of the bezel to get access tot he menu bar.
the painters tape in the above picture was showing me what I needed to trim off the bezel after I remolded the bottom opening. I have some filling and sanding to do to it and then I need to paint it again..

The tuner will wire into the Behringer USB DAC and then the tablet will control the output volume, there are USB DVB-T Tuneres I could use, but this seemed like a nice option and I get HD, the only limit is the TuNer only has 5 presets for FM/HD and 5 for AM, the actual manual controller has 15 FM, 5 AM I think

I have been testing this on the bench and everything works so far, I just need to connect the output verify it

-=JEFF=- I think you will be the first to do so in our ZR-1

How tight is the fit from side to side with the power source and interface cables?
Very interesting install.

I am not sure, I have not gotten that far, but the only connection will be the USB. The USB will be to the right. I will check to see space as soon as I get the mount solid.

Looking at closer it will be tight, I might need a right angle adapter

That was my thought. Once again it will be an interesting build. It would be nice to be able to use my all access plan in all of my vehicles for one price a year.

One downside (maybe).. for the set-up I have I need a separate volume control. The Tuner volume will not change when I adjust the tablet volume, which makes sense as the RCA Audio goes directly into the USB DAC from the tuner. Any audio out form the tablet I can adjust the volume, many will use a 1/2 DIN sized EQ. the Clarion EQS746 seems the unit of choice, but there really is no room for it to be conveniently located, I think you could mod it and have remote volume from it, but I bought a simple rca volume attenuator to go in line with my set up

I am also adding a older piece of equipment, Phoenix Gold PLD1, this is a line driver, output from the DAC will feed the PLD, then to the Attenuator (volume control) and then to the amps.

I have not decide where to mount the control yet.

Cool project Jeff

You might want to check out these apps as well. I use them on my droid phone and they work well.

Car dashboard
Poweramp
Sygic

I'd love to see how this project progresses if you have time to update us.

Thanks

Dave
